The Crocodile Hunter: Collision Course is a 2002 adventure comedy film based on the nature documentary television series The Crocodile Hunter. It stars Steve Irwin, his wife Terri Irwin in her film debut, Magda Szubanski and David Wenham, and was directed by frequent Irwin collaborator John Stainton. Released in between the series' fourth and fifth seasons, Collision Course follows Steve and Terri attempting to save a crocodile from "poachers", unaware that the two men are actually American CIA agents on their trail as the crocodile has unwittingly swallowed a satellite tracking beacon. This was Steve Irwin's final film appearance before his death in 2006.

A nature documentary or wildlife documentary is a genre of documentary film or series about animals, plants, or other non-human living creatures. Nature documentaries usually concentrate on video taken in the subject's natural habitat, but often including footage of trained and captive animals, too. Sometimes they are about wildlife or ecosystems in relationship to human beings. Such programmes are most frequently made for television, particularly for public broadcasting channels, but some are also made for the cinema. The proliferation of this genre occurred almost simultaneously alongside the production of similar television series which is distributed across the world.
