Continuity mistake: During the big sex scene you see red marks on Michael Douglas's back. These red marks are from when Sharon Stone scratches him. The thing is, she scratches him a minute AFTER you see the red marks on him for the first time.
Basic Instinct (1992)
Ending / spoiler
Directed by: Paul Verhoeven
Starring: Michael Douglas, Sharon Stone, Jeanne Tripplehorn, George Dzundza
Although you find out that the detective's girlfriend, Beth, the psychiatrist played by Jeanne Tripplehorn, had an unhealthy obsession with Sharon Stone, it turns out that Sharon Stone is the murderer... the last shot is the ice pick under her bed. Also that was Catherine Trammell and not Beth murdering the guy in the opening scene. Catherine framed Beth for it all.

Nick: How did you feel when I told you Johnny Boz had died, that day at the beach?
Catherine: I felt somebody had read my book and was playing a game.
Nick: But you didn't hurt.
Catherine: No.
Nick: Because you didn't love him.
Catherine: That's right.
Nick: Even though you were fucking him.
Catherine: You still get the pleasure. Didn't you ever fuck anybody else while you were married, Nick?
Trivia: Director Paul Verhoeven actually has a PhD in mathematics. He received it back in the 1960's in Holland. He left the field and became a film director. (From Director's commentary on "Basic Instinct: The Original Director's Cut".).
Question: Why did Catherine target Nick? I know he's a big douchebag, but that can't be the only reason right? Was it to get revenge against Beth for once and all for leaving her?
Answer: Because she's insane? And very ill. And dangerous. A pure bred psychopath. She got off screwing with him, his head. She has a degree in effing with you. Beth was just a bonus. Unlucky. Collateral damage. Unfortunate. Catherine was, is a clinical psychopath. She had no reason. Or it was fun for her. She was one twisted broad. An evil dame. (IMHO).
Answer: No definitive answer is given in the film. Catherine didn't need a reason for anything that she did. As for Beth, that was just a bonus, or a coincidence. It could be argued that Catherine targeted Beth, and Nick was just unfortunate to be involved with Beth.
