Basic Instinct (1992)

Continuity mistake: During the infamous leg un-crossing scene when Sharon Stone is being interrogated, a cigarette in her hand disappears and then reappears.

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.

Continuity mistake: During the interrogation scene, Stone has her legs crossed right over the left then suddenly left over the right and a second later (during the shot where she wears no underwear) right to left again.

Trivia: Director Paul Verhoeven approached Peter Weller for the role of Nick Curran but the producers opted for Michael Douglas instead.

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".).

Trivia: Before Sharon Stone was cast as Catherine, Michelle Pfeiffer, Julia Roberts, Kim Basinger, Kelly McGillis, Greta Scacchi, Emma Thompson and Mariel Hemingway all turned down the role.

Gus: I thought you said he was a rock and roll star.
Lt. Walker: He was a retired rock and roll star.
Capt. Talcott: A civic-minded, very respectable rock and roll star.
Gus: What's that over there?
Nick: It looks like some civic-minded, very respectable cocaine to me, Gus.

Nick: So where is this going?
Catherine: Ask me "What do you want from me Catherine?"
Nick: What the fuck do you want from Catherine?

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?

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?

Question: Did Stone have a motive for all that she did or was she nuts and doing it all for fun?
