Continuity mistake: When Prof. Rosa calls Cole, Terry answers the phone and places Rosa on hold. However, when Cole takes the phone from Terry, he does not take Rosa off of hold and proceeds to talk to him.

Trivia: When Cole is beating up Ben for counting cards, before it changes to the next scene, you can see Cole's arm stop for a brief second, which gives away that there is more to that scene.

Question: What was the club they went to in the middle of the movie? Not the strip club, it was a dance club. The entry was a long hallway with red lights inside, then it opened up to the big dance area. Does anyone know? Thx.
