Deliberate mistake: In the scene with all the coffins and new Skull "recruits", Lucas knocks on the unopened coffin and Caleb pops up. The next shot is a wider shot that shows everyone standing around Caleb's coffin, but the guy in the coffin is not the actor playing Caleb, but a stand-in.

Directed by: Rob Cohen
Starring: Paul Walker, Leslie Bibb, Joshua Jackson, William Petersen, Hill Harper
Continuity mistake: Luke McNamara is handcuffed behind his back at the police station but as he is loaded in to the ambulance he mysteriously is cuffed in front. [The handcuffs inside are normal police issue handcuffs and outside as he's getting into the ambulance they're attached to a belt, normally used for criminals they consider dangerous.]
Senator Ames Levritt: We live by the rules, we die by the rules.
