According to this other question and answer thread that cites this interview with Stephen Altobello, the famous “Wilhelm Scream” is featured in A Star is Born (1954); bold emphasis is mine:
Whoever put it in the movie in the background for one scene, that's fine; that was probably expected. But whoever found a way to weasel it into the arrangement of a Judy Garland song, that's somebody who really pulled off the ultimate, I think, because the movie stops and it's the only thing that's happening. I'll never be able to pull that off.
