Other mistake: Dan and Alex go to what looks to be Alex's apartment after meeting at the office and going for a drink. After romping around in bed, they go dancing, and on the way back through the meat-packing district, she leads him to the door of her apartment and tells him she lives upstairs and he says something like, "this is your building?" It seems odd as they were just up there having sex.

More mistakes in Fatal Attraction
Dan Gallagher: Do you remember the girl, who came to the apartment?
Beth Gallagher: The one with the blond hair.
Trivia: The opera that Glenn Close buys the tickets for is Madame Butterfly. That is the song she is listening to when we see the first signs that she is losing it. Note: At the end of Madame Butterfly the heroine kills herself over a lover. In the director's cut of Fatal Attraction Glenn Close cuts her throat in the bathroom of Michael Douglas' house thereby killing herself over a lover.
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.
