Mark Gatiss (1966 -)
- Fear of Fanny (2006) [Johnnie Cradock ]: Dies of unspecified causes in the hospital.
- Dr. Terrible's House of Horrible: Frenzy of Tongs (2001) [Hang Man Chang]: Attempts to flee the sewer in his boat but Steve Coogan throws a map drawn in black bean sauce onto it, causing crabs to overturn his boat and devour him.
- Doctor Who: The Lazarus Experiment (2007) [Richard Lazarus]: Falls to his death from a church bell tower after David Tennant uses his sonic screwdriver to amplify the sound of the pipe organ, causing Gatiss to lose his grip and fall; having been portrayed by CGI for most of this final scene, Mark reverts to human form after his death.
- Psychoville: David and Maureen (2009) [Jason Griffin]: Strangled to death with a necktie by Steve Pemberton after he discovers David Smallbone's body; the camera pans away as we hear the sounds of the struggle.
- The Crimson Petal and the White: Episode #1.2 (2011) [Henry Rackham Junior]: Commits suicide by burning his Bibles and setting himself on fire while he's fantasizing about having sex with Shirley Henderson.
- Good Omens: Hard Times (2019) [Mr Harmony]: Killed during the London Blitz when a bomb (redirected by David Tennant 's supernatural powers) lands on the church he and Steve Pemberton are meeting in. His body is later seen when David prises the books out of Mark's hands and returns them to Michael Sheen (played for laughs).
