Chillerama is a 2011 American horror comedy anthology film consisting of four stories (or segments) that take place at a drive-in theater playing monster movies. Each segment is a homage to a different genre and style.

The first is "Wadzilla" and was directed and written by Adam Rifkin spoofing 1950s monster movies. The second segment is "I Was a Teenage Werebear" and was directed and written by Tim Sullivan which parodies Rebel Without a Cause and Grease and is set in the American 1960s. The third is called "The Diary of Anne Frankenstein" and was directed and written by Adam Green and spoofs Frankenstein and The Diary of Anne Frank. The last segment is "Zom-B-Movie", a spoof of zombie films, and was directed and written by Joe Lynch.
