Movie Foreshadowing

The other day I saw "The Crying Game," a movie I'd seen a few times before but not any time recently. I was intrigued by one of the early scenes where Forrest Whittaker, still a captive of the Irish Republic Army, needs to pee. Since Stephen Rea refuses to untie Whittaker's bound hands, Whittaker asks if Rea will at least undo his (Whittaker's) zipper and facilitate the urinating process. When Rea expresses reluctance to handle Whittaker's manly apparatus, Whittaker exclaims "It's just a piece of meat!"

Having seen the movie before, I now recognized this scene as a clever bit of foreshadowing. (I won't spoil anything for any of you who haven't seen the movie yet.) It made me wonder what other foreshadowing moments others have noticed in their movie-watching. Are there similarly clever moments you can think of in other movies?
