Steve Irwin has a stunt-double came: when Wingnut steps in an Australian swamp and a crocodile jumps out and chases him in a shot where his face is not shown, mainly just his legs are shown, it is Irwin's legs that are holding Wingnut's surfboard. The crocodile in the scene was Mary, and it was filmed at Australia Zoo.
The plane crashing on the beach wasn't planned.
Shot over the course of two years.
