Wilhelm Scream

So here's a piece of movie trivia. Apparently there was a scream in a 50's movie that has been endlessly reused. As near as anyone can tell, it was originally recorded for the 1951 movie "Distant Drums," for the anguished cries of a man being bitten and dragged under by an alligator. However, it's named for an appearance two years later, in the 1953 movie "Charge at Feather River." In this case, a character by the name of Wilhelm is filling his pipe, and emits a bloodcurdling scream when he's shot by an Indian's arrow.Ben Burtt the sound designer apparently usees this scream in every movie he works on. And as he's worked on every Star Wars movie nerdy fan boy types have put together whole wbsites about it so that nerdy types like me can send it round the internet. [some geek actually put together a compilation of clips where it is used but I couldn't find a working link for that...]
