Simon Pegg

Pegg's early appearances in TV series and films include Six Pairs of Pants (Meridian & Anglia, 1995), Asylum, Faith in the Future, Big Train and Hippies. Between 1998 and 2004, Pegg was regularly featured on BBC Radio 4's The 99p Challenge. Pegg's other credits include appearances in the World War II mini-series Band of Brothers; the television comedies Black Books, Brass Eye and I'm Alan Partridge; and the films The Parole Officer, 24 Hour Party People, and Guest House Paradiso. He played various roles during the tour of Steve Coogan's 1998 live stage show The Man Who Thinks He's It.

In 1999, he created and co-wrote the Channel 4 sitcom Spaced with Jessica Stevenson. The series was directed by Edgar Wright, with whom Pegg and Stevenson had previously worked on Asylum, and Pegg wrote the character of Mike Watt specifically for his friend Nick Frost. For his performance in this series, Pegg was nominated for a British Comedy Award as Best Male Comedy Newcomer. The experience of making a Spaced fantasy sequence featuring zombies led to Pegg and Wright co-writing the "romantic zombie comedy" film Shaun of the Dead, released in April 2004, in which Pegg also starred. At George A. Romero's invitation, Pegg and Wright made cameo appearances in Romero's zombie film, Land of the Dead. In 2004, Pegg guest-starred in a spin-off of the television show Danger! 50,000 Volts! called Danger! 50,000 Zombies!, in which he played a zombie-hunter named Dr. Fell.

He played mutant bounty hunter Johnny Alpha, the Strontium Dog, in a series of Big Finish Productions audio plays based on the character from British comic 2000 AD. Pegg also appeared in Big Finish Productions' Doctor Who audio story Invaders From Mars as Don Chaney, and appeared in the Doctor Who television series, playing the Editor in the 2005 episode "The Long Game". He also narrated the first series of the "making-of" documentary series Doctor Who Confidential.

Upon completion of Shaun of the Dead, Pegg was questioned as to whether he would be abandoning the British film industry for Hollywood, and he replied, "It's not like we're going to go away and do, I don't know, Mission: Impossible III", picking the title of an imaginary blockbuster. When the film Mission: Impossible III was subsequently made, Pegg appeared in it as Benji Dunn, an IMF technician who assists Tom Cruise's character Ethan Hunt. He has reprised the role in four further Mission: Impossible sequel films: Ghost Protocol (2011), Rogue Nation (2015), Fallout (2018), and Dead Reckoning Part One (2023), and will appear in the upcoming eighth film in 2025.

In 2006, he played Gus in Big Nothing alongside David Schwimmer. The same year, Pegg and Wright completed their second film, Hot Fuzz, released in February 2007. The film is a police-action movie homage and also stars Nick Frost, in which Pegg plays Nicholas Angel, a London policeman transferred to rural Sandford, a fictional village where grisly events take place. In 2007, Pegg starred in The Good Night (directed by Jake Paltrow) and Run Fatboy Run directed by David Schwimmer and co-starring Thandie Newton and Hank Azaria. In 2008, he wrote the dialogue for an English language re-release of the cult 2006 animated Norwegian film, Free Jimmy. Pegg received screenwriting credit for this, and also voiced one of the main characters in the English-language version, which has an international range of actors including Woody Harrelson.

Pegg co-wrote the script for a film called Paul, about two young men who encounter a comedic extraterrestrial alien during a road trip across the US. The completed script appeared on the 2008 "Brit List", a film-industry-compiled survey of the best unproduced British screenplays, inspired by the American Black List. In those films and in Spaced, Pegg typically plays the leading hero while Frost plays the sidekick. However Paul reverses this dynamic. The film was released in 2011.

Pegg played engineer Montgomery "Scotty" Scott in Star Trek, the eleventh film in the Star Trek film series, released 8 May 2009. He reprised the role in Star Trek Into Darkness (2013) and Star Trek Beyond (2016), also co-writing the latter. In 2010 he appeared as William Burke in Burke & Hare, a film directed by John Landis about two Ulstermen who were notorious murderers and bodysnatchers in early 19th-century Edinburgh. His likeness was also used for the character of Wee Hughie in the comic book series The Boys; while this was done without Pegg's permission, he quickly became a fan of the title, and even wrote the introduction to the first bound volume. He voiced Reepicheep, the heroic mouse in Chronicles of Narnia: Voyage of the Dawn Treader.

Pegg and Wright completed the Three Flavours Cornetto trilogy (the first two films being Shaun of the Dead and Hot Fuzz) with their 2013 film The World's End. In July 2014, Pegg appeared on stage with Monty Python during their live show Monty Python Live (Mostly) held at the O2 Arena, London. He was the special guest in their "Blackmail" sketch. In 2015 he appeared in Star Wars: The Force Awakens as Unkar Plutt, the Junkyard dealer on Jakku.

Pegg voiced Professor Phineas Nigellus Black in the 2023 video game Hogwarts Legacy.

In May 2023, Pegg was interviewed by Lauren Laverne on the long running BBC radio programme Desert Island Discs.
