LONDON - Cartoon characters and a shop mannequin on a toilet are among the nominees for Britain's contentious Turner Prize for art.

Organizers on Tuesday named four artists competing for the 25,000-pound ($50,000) prize. It is awarded annually to a British artist under 50. Mark Leckey uses images from "The Simpsons," the movie "Titanic" and the cartoon character Felix the Cat in his film-based installations.

Cathy Wilkes is nominated for a work featuring a mannequin on a toilet with a bowl of dried porridge at its feet. Also nominated are film and video artist Runa Islam and installation artist Goshka Macuga.

Previous winners of the provocative prize include "Brit Art" upstarts Damien Hirst and Chris Ofili.

This year's winner will be announced Dec. 1.
