Theatresports is organised improvisational theatre, where teams of players perform brief 'games' for points. The games are all designed to provide a framework to allow the players' improvisional talents to shine. Developed by director Keith Johnstone in Calgary, Alberta, in 1977, he owns the copyright and trademark. As seen on TV:
- Whose Line Is It Anyway?
- Thank God You're Here
- Comedy Sportz
- Theatresports, run during the 80s on the Australian Broadcasting Corporation, launching the careers of Andrew Denton, Glenn Robbins and Shaun Micaleff
- Fast And Loose, short-lived BBC show from 2011 hosted by Hugh Dennis. The chief novelty was having one of the scenes done against a green screen- flat on the floor, so that performers have to wriggle across the floor to move around, but make it look like they are walking...
- Celebrity Theatresports, part of the Melbourne Comedy Festival.
