Diary of a Cannibal (also known as Cannibal) is a 2007 German-American horror film directed by Ulli Lommel. It is possibly inspired by Armin Meiwes, the "Rotenburg Cannibal". Lommel's film changes the account from a "Rotenburg Cannibal" to a young Los Angeleno girl who is corrupted by her new lover, a man who talks her into killing and eating him. The film has gained infamy for its highly scathing reception by critics and audiences, and has occasionally appeared in a few lists of the worst films ever made.
