Continuity mistake: Tris tries to seduce Nick at the river by dancing in front of the headlights of his car. He decides to abandon her, and backs the car away. When he cranks the steering wheel clockwise and points the car up river to leave, the camera cuts to a shot of Tris standing by the river, but the headlights are still on her.
Factual error: When Nick leaves from his home in New Jersey to play a gig with his band in New York City, an exterior shot shows his car traveling on the multi-lane ramp that serves the Lincoln Tunnel. On this ramp, vehicles must be heading into the tunnel toward NYC, or exiting the tunnel from NYC. Nick's car is shown arriving from NYC into New Jersey- the wrong direction.
