I'd hope most of have vaguely heard of the Wilhelm scream. It's a well known thing for movie buffs and the like - back in the 1950s (or thereabouts) it was recorded as part of several screams to be used for various characters in a film. The use of that sound in particular was revived for use in Stars Wars and several other films where Lucasfilm were involved in some way.
B3ta pointed out a YouTube video which compiles several of these from various films, which I think dates from before "The Phantom Menace" was available on DVD as it looks like a pirate to me.
For more sound-design clichés, see "Castle Thunder" (which I'm using at the pantomime in Biggar just now), the cry of the red-tailed hawk (which appears in every desert/wilderness scene), and also Universal's telephone ring (listen to that analogue-tape pitch wobble).
