James McAvoy has opened up about a frightening medical emergency that left him fighting for his life after a lung biopsy went wrong in 2017. The Scottish actor, now 47, recalled how his lungs collapsed while he was alone at home, just two days after undergoing a procedure to investigate a potentially concerning shadow on his lung.
The Atonement star shared the details during an appearance on Dax Shepard’s Armchair Expert podcast, describing an ordeal that resulted in weeks in hospital, an infection and a difficult period of rehabilitation before he could return to the physical demands of his acting career.
The biopsy was initially undertaken to determine whether the shadow detected in his lung was cancerous. McAvoy said the results ultimately ruled out cancer, providing the reassuring news he had hoped for. However, complications following the procedure turned what had begun as a diagnostic investigation into a life-threatening experience.
Speaking on the podcast episode released on Monday, October 12, 2026, McAvoy recalled the severity of the situation. “But that was botched, and I nearly died,” he said, describing the complications that followed the biopsy.
The actor’s account, reported by HELLO! journalist Faye James, offers a rare glimpse into a health crisis that occurred away from the public eye while he was preparing for one of his major film roles.
James McAvoy Recalls Terrifying Lung Collapse at Home
McAvoy said doctors had discovered a shadow on his lung and recommended a biopsy to establish whether it was cancerous. Although the results were negative, he subsequently experienced a serious complication that left him in urgent need of medical attention.
“I had a lung puncture… they saw a shadow in my lung, so they wanted to biopsy it to see if it was cancer, which it wasn’t, which was great,” he explained during the conversation with Shepard.
The relief of receiving a negative cancer result was followed by an unexpected and dangerous turn. According to McAvoy, he was back at home when, two days after the procedure, his lungs collapsed while he was in bed.
“But that was botched, and I nearly died. I was at home two days later, and my lungs just collapsed in bed one night. And I was on my own as well, so it was crazy,” he recalled.
Being alone made the experience particularly frightening. The incident happened outside a hospital setting, with no one immediately beside him as the medical complication unfolded.
McAvoy did not describe every detail of what happened during those hours, and his account does not establish precisely how the emergency was managed. Nevertheless, his recollection makes clear that the consequences of the biopsy were far more serious than he had anticipated.
The episode also highlights the uncertainty that can accompany medical investigations. A procedure intended to determine whether a potentially concerning finding is cancerous can involve its own risks, even when the original condition being investigated is ultimately ruled out.
In McAvoy’s case, the absence of cancer did not mean the ordeal was over. Instead, the complications required an extended period of hospital treatment and recovery.
Infection Complicated James McAvoy’s Recovery
McAvoy said he spent approximately two to three weeks in hospital following the lung collapse. His recovery was further complicated by an infection, which made treatment more difficult and prolonged the period before he could return to normal physical activity.
According to his account, the initial attempts to address the problem were unsuccessful. Doctors eventually discussed a more invasive operation to clean out the affected area after other approaches had failed.
His recollection illustrates how a serious complication can create a chain of additional medical challenges. The immediate problem required attention, but the infection introduced another obstacle, leaving the actor facing the possibility of further surgery.
McAvoy has not publicly detailed every aspect of the medical treatment he received during the episode in the material reported by HELLO!. It would therefore be premature to draw conclusions about the precise surgical techniques involved or the decisions made by individual clinicians.
What is clear from his own description is that the experience was severe enough to disrupt his physical preparation for an important film role. The hospital stay was only one part of the process; rebuilding his strength afterwards became a separate challenge.
The incident also occurred at a significant point in his career. McAvoy was preparing to return to a character whose physical transformation had already become an important feature of his work in the psychological thriller franchise created by filmmaker M. Night Shyamalan.
Returning to Fitness Before Glass
At the time of the health scare in 2017, McAvoy was preparing for Glass, the 2019 film that brought together characters from Shyamalan’s Unbreakable and Split.
McAvoy had played Kevin Wendell Crumb in Split, a character whose dissociative identities include the physically imposing Beast. The sequel gave the actor further opportunities to explore that identity, including scenes that required him to appear muscular and physically powerful.
According to HELLO!’s account of the podcast conversation, McAvoy approached Shyamalan about working with a trainer to prepare for the role. However, following his hospitalisation, his immediate priority was no longer building muscle. It was recovering the basic physical capacity needed to exercise safely.
The difference between those objectives was considerable. McAvoy explained that although he could walk, more demanding activities such as running, jogging and cycling were beyond him at that stage of his recovery.
His return to training therefore began with rehabilitation rather than conventional bodybuilding.
For the first four weeks, he concentrated on functional movement and rebuilding his physical capabilities. Only after that initial phase did the programme progress towards developing the muscular appearance required for Glass.
The gradual approach reflects the distinction between recovering from a significant medical event and preparing for a demanding screen role. An actor may need to meet a particular physical standard for a production, but that goal cannot simply replace the work required to regain strength and mobility.
McAvoy credited the trainer who helped guide him through the process, saying: “The guy that worked with me was amazing.”
His comments suggest that the early stages of recovery required patience and a focus on foundational movement before he could resume the more specialised training associated with the character.
The experience also provides context for the physical preparation behind Glass. The transformation audiences saw on screen was not simply a matter of increasing muscle mass. For McAvoy, the process followed a serious health complication that had temporarily limited even ordinary exercise.
Why Kevin Wendell Crumb’s Physicality Mattered in Glass
McAvoy’s preparation was particularly relevant because Kevin Wendell Crumb is one of the central figures in Shyamalan’s interconnected thriller universe.
In Split, released in 2016, the actor portrayed a man whose different identities have distinct personalities and characteristics. The film also introduced the Beast, an identity associated with exceptional physical strength and a more imposing appearance.
Glass, released in 2019, continued that story while bringing McAvoy together with Bruce Willis and Samuel L. Jackson. Willis returned as David Dunn, the central character from Unbreakable, while Jackson reprised Elijah Price, also known as Mr. Glass.
The crossover brought together the principal figures from the two earlier films and placed McAvoy’s character within a broader confrontation over the possibility of extraordinary human abilities.
For the actor, that meant continuing a performance that depended on more than changes in voice, posture and expression. The physical distinction between Kevin’s identities was also part of the character’s presentation, making his return to strength an important element of the preparation process.
McAvoy’s account does not suggest that the medical emergency changed the film’s storyline. Rather, it explains the personal circumstances surrounding his preparation for the role and the rehabilitation that preceded his return to more demanding exercise.
The timing is significant because the health scare happened before filming Glass, rather than during the film’s release period. His recovery therefore formed part of the less visible work that had to take place before he could meet the production’s physical requirements.
From Scottish Childhood to International Film Stardom
Although the podcast conversation included McAvoy’s medical emergency, the discussion also explored other aspects of his life and career, including his upbringing in Glasgow and the experiences that shaped his approach to acting.
Born in Glasgow in 1979, McAvoy developed from a Scottish performer working across stage and screen into an internationally recognised actor. His career has included independent films, major studio productions, period dramas, comedies and psychological thrillers.
One of his best-known performances came in Atonement, the 2007 romantic war drama in which he starred opposite Keira Knightley. The film brought him wider international attention and demonstrated his ability to move between intimate character work and larger cinematic productions.
He subsequently appeared in a broad range of projects, including the X-Men film series, in which he portrayed a younger version of Charles Xavier, and Shyamalan’s Split and Glass.
His work has often required significant changes in characterisation, whether through physical preparation, accent, movement or the emotional demands of a particular role. His account of recovering before Glass adds another dimension to understanding the practical demands behind that work.
However, McAvoy’s willingness to discuss the experience on Armchair Expert should not be mistaken for a comprehensive disclosure of his medical history. The details reported by HELLO! relate specifically to the lung biopsy, its complications and his subsequent recovery.
The actor is known for maintaining a degree of privacy around his personal life, making the podcast discussion a relatively uncommon opportunity to hear him reflect on a frightening experience away from the film set.
James McAvoy’s Directorial Debut Marks a New Career Chapter
The podcast appearance also touched on McAvoy’s latest professional milestone: his move into directing with California Schemin’.
The film tells the story of two aspiring rappers from Dundee who reinvent themselves as Americans in an effort to gain entry into the music industry. Based on a true story, the project draws on a real-life episode involving ambition, identity and the lengths performers may go to in pursuit of a breakthrough.
According to HELLO!, the film received its UK gala premiere at the Glasgow Film Festival and opened in cinemas across the UK and Ireland in April.
The project represents a different kind of responsibility for McAvoy. As an actor, he has spent decades interpreting characters within productions shaped by directors and other creative collaborators. Taking the director’s chair places him in a position to oversee performances and contribute to the broader creative decisions that shape a film.
The choice of a story rooted in Dundee also connects the project to Scotland, the country where McAvoy grew up and began his career. Although the film’s subject is distinct from his earlier acting work, its focus on performers trying to find their place in a competitive industry offers a story about ambition and reinvention.
His discussion of the directorial debut, alongside his memories of Glasgow childhood and his experiences working with fellow actors, gave the podcast conversation a broader scope than the medical emergency alone.
Taken together, those subjects trace different stages of a career that has moved from Scottish beginnings to international film productions and, now, directing.
A Private Family Life Away From the Spotlight
McAvoy has also generally kept his family life out of the public spotlight. He shares his eldest child, Brendan, who was 15 at the time of the account, with his first wife, actor Anne-Marie Duff.
The couple married in 2006 and separated in 2016, ending a decade-long marriage. Both have maintained professional careers, and McAvoy has typically avoided making his children a central feature of his public appearances.
In 2021, he offered a rare glimpse into his approach to parenting in an interview with Screen Rant, as noted in HELLO!’s report. The actor has since welcomed a second son, although he continues to keep many details of his family life private.
McAvoy is married to Lisa Liberati, with whom he has also largely kept his relationship away from extensive public discussion. The couple tied the knot in a private ceremony, according to the reporting cited by HELLO!.
His preference for privacy provides context for why the account of his 2017 health emergency stands out. While he regularly discusses his work as an actor, details of a frightening personal experience that occurred while he was alone at home have not been a routine part of his public profile.
The podcast offered him an opportunity to revisit the episode in his own words, connecting it to the professional challenges that followed.
The Lasting Significance of McAvoy’s Health Scare
Looking back, the 2017 lung complication sits at the intersection of McAvoy’s personal health and his professional obligations. A biopsy undertaken to investigate a possible cancer diagnosis produced reassuring results, but the complications that followed left him facing a serious medical emergency.
His account describes a collapse at home, an extended hospital stay, an infection and a rehabilitation period that began with basic movement before progressing towards the physical requirements of Glass.
It also underlines how little of an actor’s preparation is visible to audiences. Viewers see the finished performance, the character’s physical appearance and the dramatic moments that make it to the screen. They rarely see the recovery, training adjustments and personal challenges that may precede filming.
McAvoy has not presented the experience as a detailed medical case study, nor has the account reported by HELLO! supplied enough information to independently assess the precise cause of every complication. The most direct understanding of the event comes from the actor’s own recollection on Shepard’s podcast.
What that recollection establishes is that the consequences were serious, that his recovery took time and that returning to the physical demands of acting required a measured process.
His gratitude towards the trainer who helped him regain his capabilities also points to the importance of support during that process. The initial weeks were dedicated to rehabilitation, not immediately recreating the muscular physique associated with the Beast.
Nearly a decade after the incident, McAvoy’s decision to discuss the experience offers a reminder of the unpredictable circumstances that can sit behind an otherwise familiar film career. The cancer concern that prompted the biopsy proved unfounded, but the procedure’s reported complications created a separate crisis that he says nearly cost him his life.
For an actor whose work has taken him from intimate dramas to physically demanding thrillers, the episode remains a striking account of how quickly circumstances can change—and how much work may be required before life and professional ambitions can return to something approaching normality.
