The titular bus is a nuclear-powered, articulated double-decker, so big that it even has a pool and bowling alley and makes its first appearance on screen to 2001 music. Our hero is a down-on-his-luck driver who’s reputed to have eaten all his passengers when he was the only survivor of a previous wilderness bus catastrophe (he says he only ate a single foot). Now, at the wheel on a non-stop trip from New York to Denver, he has to deal with all manner of problems, including an on-board bomb, a love affair and a motley busload of crew and characters. My own favourite is the lounge piano guy who keeps smiling and playing no matter how bad things get. The convincing cliff-edge finale in the Rocky Mountains even outdoes The Italian Job. The movie plays with the tropes of all kinds of films, not just disaster. Film buffs will love it.
