Basic Instinct

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.

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.

Question: Why did Catherine change her mind about killing Nick at the end? Obviously she was planning on killing him anyway, but she changed her mind only hours after ending their relationship when her book was finished and was of no further use. So why did she spare him? Was it because she fell in "love" with him?

Answer: There's no definitive answer to this and the ending is deliberately ambiguous and open to interpretation. The audience is left to speculate whether or not Catherine kills Nick, or if she intended to kill him but changes her mind because she loves him, or intends to kill him at a much later time, and so on.
