Seven facts that define the man behind the comedy:

What has happened to Simon Pegg?

Recent public appearances and career updates

Simon Pegg remains active in two of the biggest film franchises on the planet. He is set to reprise his role as Benji Dunn in Mission: Impossible – The Final Reckoning (2025) and has appeared in the fourth season of The Boys as a surprise cameo, playing a fictionalised version of himself (BBC News (public broadcaster)). His production company, Stolen Picture, continues to develop original projects.

Key events in 2023–2024

• 2023: Pegg revealed on BBC Radio 4’s Desert Island Discs that he had hidden his alcoholism from colleagues while filming Mission: Impossible.
• 2024: He completed press for Mission: Impossible – Dead Reckoning Part One and began filming the sequel.
• 2025: In a Variety interview, Pegg spoke about how his sobriety and fitness routine have transformed his outlook on life (Variety (entertainment news outlet)).

The implication: Pegg turned vulnerability into a career anchor, using the same discipline that drives his fitness to sustain his professional momentum.

Are Tom Cruise and Simon Pegg friends in real life?

On-screen vs off-screen camaraderie

They play colleagues who distrust each other on screen, but off camera, the bond is genuine. Pegg has said that Cruise “took me under his wing” and encouraged him to get fit for the role of Benji. Cruise even provided a personal chef on set, with Pegg noting that the meals were carefully prepared rather than bland diet food.

Public statements about their friendship

In a 2025 interview, Pegg described Cruise as “one of the most generous people I’ve ever met” and credited the Mission: Impossible franchise with helping him find purpose during his recovery from alcohol dependence. Cruise, for his part, has called Pegg “a brilliant actor and a real friend” (MTV News (music and entertainment channel)).

The implication: Their friendship is not Hollywood PR. It’s built on shared experiences, including gruelling physical training and the pressure of delivering blockbuster performances.

Is Simon Pegg still sober?

Pegg’s history with alcohol

Simon Pegg has been open about his struggles with alcohol. In 2023 he told The Guardian that he began drinking heavily in his twenties and kept his alcoholism secret while working on Mission: Impossible. He hit a low point in 2010, which prompted him to quit.

His decision to quit drinking

Pegg says he stopped drinking in 2010 after recognising that alcohol was damaging his health and family life. A 2025 Variety profile describes him as “sober for 15 years and counting.” He also credited the Mission: Impossible films with giving him the focus to turn his life around.

The pattern: Recovery gave Pegg structure, and that structure became the engine for both his physical transformation and his continued relevance in blockbuster cinema.

Why did Simon Pegg lose so much weight?

Reported weight loss of 20 lbs

Pegg first shed about 20 pounds for a reshoot of Mission: Impossible – Ghost Protocol involving a Red Square scene. He later dropped another 20 pounds for the 2020 thriller Inheritance, reducing his body fat from 12% to 8% (Men’s Journal (men’s lifestyle magazine)). That transformation was so extreme that his wife, Maureen, told him she “hated” his gaunt appearance (Sky News (UK news broadcaster)).

His workout and diet regime

Pegg says he “first rediscovered keeping in shape” on Ghost Protocol (Hollywood Authentic (celebrity interview site)). He now follows a high-protein, low-carb diet and trains with resistance exercises and cardio. He continues to use Cruise’s travelling on-set gym, which the star brings to every Mission: Impossible location.

The catch: Pegg’s weight loss is not a quick fix for a single role—it’s part of a permanent lifestyle shift that began when he quit drinking and decided to take care of his body.

Who is Simon Pegg’s best friend?

Longtime friendship with Nick Frost

Nick Frost is universally regarded as Pegg’s closest friend. The two met in the 1990s, lived together, and co-created the cult TV series Spaced. They went on to star in the Cornetto Trilogy (Shaun of the Dead, Hot Fuzz, The World’s End) and have appeared in dozens of projects together. Frost has described Pegg as “the brother I never had” (The Independent (UK newspaper)).

Other close industry friends

Beyond Frost, Pegg counts Tom Cruise and director Edgar Wright among his nearest collaborators. Wright directed the Cornetto Trilogy and has remained a close creative partner. Pegg has said that working with Wright “shaped me as a filmmaker” (Empire (film magazine)).

What this means: While Pegg has many friends in the industry, Nick Frost is the one constant through his entire career—the creative soulmate who helped launch him.

Quotes

“I discovered joy in taking care of myself after quitting alcohol. I’d never felt that before.”

— Simon Pegg, Variety (2025 interview)

“Simon is a brilliant actor and a real friend. Working with him on Mission: Impossible has been one of the great pleasures of my career.”

— Tom Cruise, MTV News

“I was hiding my drinking from everyone. The Mission: Impossible set became my anchor—it gave me a reason to get up and be disciplined.”

— Simon Pegg, The Guardian (2023)

For Pegg, the transformation is not a fluke of Hollywood pressure—it’s a deliberate, ongoing commitment. For fans who admire his work, the lesson is clear: the same discipline that drives a blockbuster actor can also drive a personal recovery. For those who struggle with similar issues, Pegg’s story offers a practical proof point: sobriety and fitness can reinforce each other, but only if you start with the hardest step—admitting you need to change. Pegg turned a mid-career crisis into a second act, proving that personal accountability can reshape both body and trajectory.
