Continuity: In the first scene of the movie Sharon Stone holds the end of her white silk scarf in her right-hand. In the next shot the end of the scarf is draped over her right hand.

Visible crew/equipment: The film crew is visible in Nick's sunglasses when he meets Hazel, the old lady.

Factual error: The road where the cops drive on their way back from the beach - where we see San Francisco in the background - is a dead end. It does not lead to Stinson Beach.

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.

Revealing: When Michael Douglas pulls his car in front of Jonny Boz' house after the initial murder we hear him come to a screeching halt. If you look closely, perfect tire skid marks can be seen in the exact same spot on the road in front of his police car before it comes to a stop.

Revealing: When Jeanne Tripplehorn meets with Michael Douglas it's obvious by the flat reflection of the studio lights that she's wearing prop glasses.

Continuity: When Nick and Gus are driving Katherine to the police station for the first time, they drive past the same stretch of coast about three times throughout the scene. Most obviously seen by the position of the small island - it jumps from being in the distance, to being even with the car, then behind the car, then in front again etc.

Factual error: The light reflections at Tremell's beach house are not the ones an ocean would make. The reflections are from large flat areas of almost calm water - like in basins - but there are none around.

Visible crew/equipment: When Michael Douglas pulls his car in front of Jonny Boz' house after the initial murder scene policemen on the far corner can be seen directing traffic away from the movie set, at the top of the hill.

Continuity: When Michael Douglas and his partner are in the diner, the cap on the Tabasco sauce bottle is off. A second later, it is on.

Revealing: Michael Douglas almost has a head-on collision with a bus as he chases Sharon Stone down the highway. If you look closely as he slams on his brakes, there are many skid marks in that exact same spot in the road from previous takes.
