Arthur Hiller's 1976 film is the epitome - and one of the best and at times, the worst - example of what Hollywood came synonymous for in the 1970s.
Ending with one of those truly great action set-pieces, when such were actually filmed and not with a computer mouse and starting out with the oh-so-smooth Gene Wilder getting his wicked way with the delectable Jill Clayburgh, an awful lot happens in-between.
Taking - and featuring huge chunks of influence from James Bond (inc 'Jaws', the iron-toothed giant), Hitchcock (crime capers on moving trains, espionage, intrigue) and loads of over-the-top big Americanism, this is a rail-road coaster of a ride. You can see bits that have helped influence later films, too and the start of the delicious pairing between Wilder and black comedian Richard Pryor, which spilled out over into the future Stir Crazy and Blazing Saddles.
Yes, a lot of it is nonsense - this is essentially Sunday afternoon TV fun, now. There's clever innuendo, dumb stunts, big scenery and baddies. It does pop up on Film 4 and Sky Movies every once in a while, showing that it is still has a place and though obviously looking pretty dated now, you can't go far wrong with this one.
