More mistakes in Fatal Attraction
Alex Forrest: You're here with a strange girl being a naughty boy.
Dan Gallagher: I don't think having dinner with anybody's a crime.
Trivia: In the cocktail party scene, there is a quick shot of the large crowd attending the party. Look closely at the dark-haired man near the front of the party goers - it's James Eckhouse, who played Mr. Walsh on "Beverly Hills 90210" He also had a similar, uncredited role as an 'extra' in the first bar scene in the movie "Cocktail."
Question: Why does Alex abduct Ellen and take her to a carnival?
Answer: Because she's unhinged! And she wants Dan to know that she can get to him, or in this case his daughter, anytime she wants. And she's angry that Dan had an affair with her then went back to his wife.
Answer: So her parents (especially her father) would go through hell, not knowing where she was or if she was safe.
