Sin City Easter Egg - Sin City Wilhelm

On a DVD player or a VCR with a timer/clock display set the movie at 15:50. Right around this time Marv (Mickey Rourke) is in a police car. After taking care of the first cop you'll see a backview camera shot of the car, where the car stops. The passenger door then opens and the second cop is thrown out. As the second cop is thrown you'll hear the scream of the Wilhelm.

For those unfamiliar with the Wilhelm, it is almost a ritual among sound editors to slip that sound track into almost any movie. The scream is of a man, but it sounds a little goofy. The sound track is at least 60 years old and I can vouch that it occurs in movies such as Star Wars Episode IV, Indiana Jones I, Hellboy, and Lord of the Rings (Two Towers and Return of the King). I know there are others who can identify more instances of this but have fun trying to find them on your own.
