There must be a variant of 7 in another movie, because I know I've heard something like it before but the movie that comes up on Google is one I've never seen before. (Either that, or they used the clip in some context where I wouldn't have associated it with the movie, such as the "Years of Great Movies" trailers they sometimes put on DVDs.)

The only one I recognized and could put in context was 2, which was already guessed.
