Craig Mazin

Mazin began his entertainment career as a marketing executive with Walt Disney Pictures in the mid-1990s, where he was responsible for writing and producing campaigns for studio films. He made his screenwriting debut with 1997's sci-fi comedy RocketMan, co-written with his then-writing partner Greg Erb. He has since written movies such as Senseless, Scary Movie 3, Scary Movie 4, and Identity Thief. He has directed two films: 2000's low-budget superhero film The Specials, which he also produced, and the 2008 superhero spoof Superhero Movie, which he also wrote (he also made a cameo appearance as a janitor).

Since 2006, Mazin has collaborated with director Todd Phillips on several occasions. He co-wrote both Hangover sequels, The Hangover Part II and The Hangover Part III, and executive produced School for Scoundrels. In 2004, he was elected to the board of directors of the Writers Guild of America, West. He did not seek re-election and his term expired in September 2006. Along with fellow former WGA board member Ted Elliott, Mazin ran a website called The Artful Writer, which focused on issues relevant to working screenwriters. It closed in 2011 after seven years. In 2011, Mazin and fellow screenwriter John August began Scriptnotes, a weekly podcast on the craft of screenwriting and the U.S. film industry.

In 2017, HBO and Sky Television announced Chernobyl, a five-part drama miniseries created by Mazin about the infamous Chernobyl disaster. The series aired in 2019 and was filmed in Lithuania and Ukraine. Mazin said that the "lesson of Chernobyl isn't that modern nuclear power is dangerous [...] the lesson is that lying, arrogance, and suppression of criticism are dangerous". In an interview with Decider, he said, "If I came to HBO and said 'I want to do another season of Chernobyl, except it's gonna be about another tragedy,' whether it's Bhopal or Fukushima or something like that, I would imagine they at least would give me polite interest."

In 2019, it was announced that Disney had hired Mazin to co-write the screenplay of a sixth Pirates of the Caribbean movie with original Pirates screenwriter Ted Elliott. He was named as the scriptwriter for the Lionsgate film adaptation of the Borderlands video game series in February 2020, though his name was removed from the project by 2023. In January 2021, Mazin signed an overall deal with HBO.

He was announced as co-writer and co-executive producer for a television series adaptation of the video game The Last of Us for HBO in March 2020, alongside the game's co-director and writer Neil Druckmann. The Last of Us adaptation was greenlit by HBO in November 2020, and was released in January 2023. In July 2025, it was announced Mazin would have creative control of the third season as Druckmann and Halley Gross exited the series to pursue other commitments.
