Continuity mistake: Sharon Stone has gone and left a note on the pillow and we see Michael Douglas's back again as he wakes up to find it. The scratch marks on his back have all healed as there are hardly any there. (01:17:10)
Visible crew/equipment: As Roxy follows Michael Douglas after he leaves Mac's Diner, the shadow of the cameraman can be seen moving on the license plate of Sharon Stone's car. (01:23:45)
Continuity mistake: When Roxy drives Sharon Stone's car off the road it lands on a yellow hose at the bottom of a construction site. When Michael Douglas runs down into the construction site the car is nowhere near the yellow hose. (01:26:10)
Visible crew/equipment: Jeanne Tripplehorn along with Dr. Myron and Dr. McElwaine meet with Michael Douglas back at the station after Roxy's death and equipment shadows can be seen moving all over the walls. (01:28:00)
Continuity mistake: Jeanne Tripplehorn walks into her apartment and Michael Douglas is there asking questions about her and Sharon Stone in college. If you look closely the pillows on the couch on the left of the screen move from the time she opens the door to when she walks into the apartment. (01:38:35)
Continuity mistake: Michael Douglas waits in the dark in Jeanne Tripplehorn's apartment and says to her after she walks in, " Tell me about Catherine". At first we see a couch and chair on the right side of the room but two shots later as he walks towards her these two items have been removed from the room. (01:38:40)
Audio problem: After Jeanne Tripplehorn is killed, Michael Douglas is back at the police station and Jack the Internal Affairs Investigator says to the black investigator, "No report from Berkeley, nothing at all about Salinas". If you look closely at his lips he's saying something else. (01:56:40)
Continuity mistake: At the end of the movie Michael Douglas goes back to his apartment to find Sharon Stone waiting for him and the chair and the items on the kitchen table move between shots without anyone going near them. (01:59:30)
Continuity mistake: At the end of the movie when Michael Douglas and Sharon Stone relax in bed contemplating their future together and the black lamp on the left side of his bed changes the direction that it's pointing in throughout the scene without anyone going near it. (02:01:00)
Continuity mistake: During the infamous leg un-crossing scene when Sharon Stone is being interrogated, a cigarette in her hand disappears and then reappears.
Plot hole: This is another movie where the cops are too dumb to go out by themselves. The woman who icepicks the first victim (we see) to death would have left enough forensic evidence on the scene to convict her ten times over - skin, hair, sweat, saliva, vaginal fluid, possibly blood, and they all contain DNA in abundance. She had vigorous, sweaty sex with this man and she didn't clean up afterwards (and she couldn't have done so thoroughly enough anyway) so she's left calling cards all over the place. The killer also handled the icepick (which the police take away in an evidence bag) with bare hands - her prints would be all over it. She might as well have left a signed confession, but they can't even identify her. Sharon Stone, for instance, leaves her fingerprints (on the chair and fixtures in the police station) and her saliva (containing epithelial skin cells which are an excellent source of DNA) on the cigarette butt she discards, also in the police station. She went there of her own accord and these artifacts are legally accessible by the police. It is obvious to anyone that the women who had sex with the victim killed him, and Catherine is most certainly a suspect. They don't have enough to charge her but they would if they did a simple series of tests on the dead man's body - and if she didn't do it, that would eliminate her as a suspect. They don't even check.
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.
Continuity mistake: In the scene where the actual murder takes place the blonde woman stabs him in the neck. The body has no blood on it. The second stab the body is covered with blood. This all happens in one eyeblink.
Continuity mistake: Douglas opens a mailbox to check the mail for clues. He then puts the mail back and closes the box, a second later you hear him closing the mailbox again.
Factual error: Michael Douglas is lying on the couch watching the Jeffersons. Jeanne Tripplehorn arrives and they talk. In the background the theme song to the Jeffersons is playing, but it is the song from the beginning of the show rather than the closing theme.
Continuity mistake: When Roxy runs off the bridge you see the Lotus crashing over with its low beams on - when you see the car fly off the bridge its brights are on.
Continuity mistake: In the sequence where Michael Douglas is driving along the coastal highway, his car's center rear-view mirror appears and disappears over and over.
Continuity mistake: When Roxy tries to run over Nick the left front light is broken off - in the next scene it is back on.
Visible crew/equipment: The film crew is visible in Nick's sunglasses when he meets Hazel, the old lady.
Answer: She is portrayed as a psychopath with an uncontrollable urge to kill.

I wouldn't say that she had an "urge" to kill. Rather, she was willing to "dispose" of people by killing them. She would kill people who were in her way or were no longer interesting/useful.
