Other mistake: In the scene where Jessica Alba has just cut off the guy's hand she was cuffed to and she is running around the boat, the handcuffs don't have a spot of blood on them.

Directed by: John Stockwell
Starring: Jessica Alba, Paul Walker, Scott Caan, Ashley Scott
Continuity mistake: In the airport scene Scott Caan introduces his new "girl" to Paul Walker and Jessica Alba. In the background behind Paul you see a long-haired brunette wearing a strapless shirt walk out of the terminal and continue past the camera. The shot changes to a wide angle of the four main characters, and a second or so after the change you see the same brunette come out of the terminal again.

Trivia: In the American version of this film Jessica Alba's bikini bottoms were digitally extended to cover her buttocks. In the European version they remain the same.
