Continuity mistake: Tony Shalhoub at the beginning of the movie sits at the bench saying that he does not like weights "because they're heavy." This takes place between 2 shots: in the second one the guy in the background wearing black tank and light pants, exercising with a red ball, suddenly is standing closer to the women at the machine, just so he can get in frame. (00:04:00)
Continuity mistake: When Pastor Randy hands Paul a glass of iced tea, the lemon slice falls off the glass to the ground, but in the next shot we see Paul drinking, the lemon slice is back on the glass. (00:24:40)
Continuity mistake: When Daniel is lifting at home and Johnny Wu is on TV you can see a red and white MET-Rx protein container with silver dolphins on it right beside the TV. The camera switches angles and it's gone, then switches back and it's there, then it's gone again.
Continuity mistake: In the scene where The Rock is escaping from the police and jumped into the water, he is being shot at by the policemen. In the camera shot that shows the bullet piercing his foot, the label on the shoe shows it's the left foot that was shot, but when he gets out of the water and is limping, it suddenly shows that his right foot was hit.
