Is it just me, or could the guy in the "bush" outfit at the airport be Steve Irwin? Call me crazy, but the guy does bear an incredible likeness. This "mystery extra" appears when "Skippy" scans the room before saying "I hate this job."
I know the guy you're talking about, and yeah that dude DOES strike a very close resemblance to the Crocodile Hunter. Almost a spitting image, I'd say. I seriously doubt it's him, though. I looked up a few Steve Irwin sites and there's nothing that says he played as an extra on any movie prior to his television career.
While we're on the subject, has anyone seen his "final video" with the stingray? He's said in the past that if he were to be killed by an animal on one of his shows that he'd wanted the entire thing filmed, so I'd imagine there's gotta be a copy or two floating around. Link, anyone?
