Drop Dead Fred is a 1991 fantasy comedy film directed by Ate de Jong, produced by PolyGram Filmed Entertainment and Working Title Films and released and distributed by New Line Cinema. Although touted as a light-hearted children's film, there are notable adult themes and gags, with elements of black comedy and gross out humor, and some profanity.

British comedian Rik Mayall stars as the title character, a happy, anarchic and extremely mischievous imaginary friend of a young girl named Elizabeth (Ashley Peldon) and arch nemesis of her fussy and overbearing mother Polly (Marsha Mason) whom he refers to as the "mega bitch". Drop Dead Fred causes absolute chaos around the home and neighbourhood. Nobody else can see Fred except Elizabeth. When Elizabeth grows up (portrayed by Phoebe Cates) and is having a mid-life crisis, Fred returns to "cheer her up" in his own unique way, causing more chaos than ever before. The supporting cast includes Carrie Fisher, Ron Eldard, Tim Matheson and Bridget Fonda.
