Ace Ventura: Pet Detective is a 1994 American comedy film starring Jim Carrey, who plays Ace Ventura, an animal detective who is tasked with finding an abducted dolphin who is the mascot of the US football team Miami Dolphins. The film was directed by Tom Shadyac, who wrote the screenplay with Carrey and Jack Bernstein. Bernstein and Bob Israel (ultimately a co-producer for the film) developed the project for almost six years. The film co-stars Courteney Cox, Tone Loc, Sean Young and former Miami Dolphins quarterback Dan Marino. The film features a cameo appearance from death metal band Cannibal Corpse.
The film was produced on a budget of $15 million. It received generally unfavorable reviews from critics. At the worldwide box office, it grossed $107.2 million. In addition to launching Carrey's film career, it also spawned the sequel film Ace Ventura: When Nature Calls (1995), the animated TV series Ace Ventura: Pet Detective (three seasons, 1995–2000), and later, the direct-to-video spin-off Ace Ventura Jr.: Pet Detective (2009).
