James Francis Gunn Jr. (born August 5, 1966) is an American filmmaker. He began his career as a screenwriter in the mid-1990s, starting at Troma Entertainment with Tromeo and Juliet (1996). He then began working as a director, starting with the horror-comedy film Slither (2006), and moving to the superhero genre with Super (2010), Guardians of the Galaxy (2014), Guardians of the Galaxy Vol. 2 (2017), The Suicide Squad (2021), and Guardians of the Galaxy Vol. 3 (2023).
In 2022, Warner Bros. Discovery hired Gunn and his longtime producer Peter Safran to become co-chairmen and co-CEOS of DC Studios. Under DC Studios, Gunn will co-produce and executive produce every film and television series under the upcoming DC Universe (DCU) media franchise alongside Safran, which will act as a soft reboot of the DC Extended Universe (DCEU). In the DCU, he is the creator of the series Creature Commandos (2024) and the writer-director of the upcoming film Superman (2025).
He also wrote and directed the web series James Gunn's PG Porn (2008–2009), the HBO Max original series Peacemaker (2022–present) and the Disney+ original special The Guardians of the Galaxy Holiday Special (2022). Other work for which he is known include writing for the 2004 remake of George A. Romero's Dawn of the Dead (1978), writing the live-action adaptation of Scooby Doo (2002), and its sequel Scooby-Doo 2: Monsters Unleashed (2004), writing and producing the horror-action film The Belko Experiment (2016), producing the superhero-horror film Brightburn (2019), and contributing to comedy-anthology film Movie 43 (2013) (directing the segment "Beezel") and the 2012 hack-and-slash video game Lollipop Chainsaw.
