Movie Assignment

My movie assignment is going to be about a guy who is walking down the street and sees this really pretty woman. He thinks it's love at first sight, so he tries to approach her to talk to her but she doesn't see him and keeps walking to her destination. The man is running past people and tripping trying to reach the lady. At the end when he finally gets to her at a stop light, he says hello and she turns around to actually just be a guy with long hair. The man who was chasing 'her' gets a bewildered look on his face and the 'woman' walks away leaving the man without a clue where he's at. (still with the bewildered look on his face.)
