Continuity mistake: In one scene we are looking at a shopping complex known as Greenspring Station which Nina is being chased through. Somehow she winds up being chased through a K-Mart. Anyone familiar with the Baltimore area, where the movie was shot, knows for a fact that there is not a K-Mart anywhere near that ritzy section of town.

All of the magazines that are on top of the set come crashing to the ground, including a TV Guide with "Get Ready For A Fabulous February" (or something like that) in big letters on the cover. Interesting since the movie is set around Christmas time.

Continuity mistake: In the scene where Shirley and her daughter Milandra argue about Shirley going on holiday, Milandra gets out of bed and dresses quickly, her shirt is tucked into her jeans.

Continuity mistake: During the "exciting" conclusion, Investigator Natsuo runs toward the villain's vehicle, jumps, and kicks through the windshield.

It is quite obvious, as the car goes from a dark red color to dull grey.
Continuity mistake: When Lurleen changes lanes to pass the Ferrari, the lane change isn't reversed when Lea sees it in the Ferrari's rearview.
