Nothing but Trouble is a 1991 American comedy horror film written and directed by Dan Aykroyd in his directorial debut, based on a story by his brother Peter, and starring Chevy Chase, Dan Aykroyd (in a dual role), John Candy (in a dual role), and Demi Moore. It tells the story of two yuppies and the clients of one of them who are taken to court for running a stop sign in the bizarre, financially bankrupt small town of Valkenvania, which is dominated by a 106-year-old judge. Tupac Shakur made his acting debut, as a member of the rap group Digital Underground.

Production commenced in 1990 under the title Git, which was changed in production to Valkenvania. Subsequently, prior to release, Warner Bros. changed the title to Nothing but Trouble; in a press statement released in December 1990, Aykroyd said that he preferred the Valkenvania title.

Upon release, the film was largely panned, with criticism directed at its humor, screenplay, tone and direction. The tone was compared by critics to films such as Abbott and Costello Meet Frankenstein, Psycho, The Texas Chainsaw Massacre series and The Rocky Horror Picture Show, as well as The Munsters, and the humor derived from sketch comedy and gross-out humor. Aykroyd received the Worst Supporting Actor Razzie at the 12th Golden Raspberry Awards.
