Revealing mistake: At the beginning of the movie, the coked-up sailor is shooting from a rooftop and screaming various racial slurs. Despite that, there's a big crowd building. When he shouts "Come and get me, honkies!" you can see people running way before he pulls out of the gun again and shoots. Not only that; some of the extras are just enjoying themselves and not keeping a straight face, far from being scared. (00:01:00)
