The other night I was watching the movie "Strangers on a Train." I don't remember the names of the characters, so I'll describe this the best I can. There is a guy who is stalking a woman so that he can kill her. The woman is at an amusement park with two other men. She and her two dates for the eveening are in the Tunnel of Love, and the murderer is in the boat behind them. There is a silhoutte of the shadows, and the man is slowly approaching the woman in the tunnel. The camera shifts to the exit, and we hear a scream. We are supposed to think the murderer attacked her in the tunnel, but when the woman's boat comes out, she is laughing, and one of the men is tickling her sides. Pretty cool scene. Plus, it's a really good movie, with a great concept. (For those of you that don't know, the concept of the movie is that there is a man with a theory that two strangers meet up, and each commits a murder for the other. Neither would egt caught, since there is no motive,a nd nothing to connect them.)
