Steve Irwin, the world’s most annoying human, gets his shot at the big screen in this version of Animal Planet’s The Crocodile Hunter. Directed by John Stainton, the movie, or what there is of it, amounts to an expanded redux of Steve’s TV show with a smattering of harebrained plot involving a top-secret satellite transmitter ("that could alter the balance of power in the world") lodged in the intestine of a nasty old croc. Also in the mix: a pair of fish-out-of-water CIA agents gone Down Under to retrieve the device; an obese, cantankerous, shotgun-wielding rancher; and a pack of maul-happy dogs. Steve-O gets his pro-environment message across early, and though his derring-do with the lethal beasties (he often seems more a peevish agitator than a caring nurturer) is daunting, his jovial chatterbox shtick wears thin fast. About 15 years ago, another Aussie-gator romp got it right with its blend of wildlife preservation, Outback mysticism, and cheeky humor. If that’s what you’re looking for, leave Steve-O on the TV and rent Crocodile Dundee. (90 minutes)
