Audio problem: In the scene where Louis is giving Shay a one-on-one training session, listen carefully from when Mr. Kerrigan walks in. Turn up the volume if you have to. You can hear one of the crew members shout "Hey Mark", referring to Mark Dacascos.
Continuity mistake: After Orlando has agreed to go with Silverio, Silverio says to the policeman "I just gotta say one little thing to my homie. I'm outta here". He is then standing very close to the cop, almost shoulder by shoulder. When the angle changes, he is suddenly standing a few feet away from the cop, before he starts moving towards Louis.
Audio problem: During the fight in the chop shop, Louis gets surrounded by four guys and grabs a pole to defend himself. After doing some initial moves with it, he blocks a few swings from another man, then turns around and swings his staff against the face of another. He does not hit the man on this swing, but the sound of the pole connecting with the guy's jaw is still there.
Revealing mistake: During the fight in the chop shop, a man with a tire iron swings at Louis and he avoids it, leading the tire iron into a switch box. The man holding the tire iron is electrocuted, but Louis is still holding onto him with his bare hands without suffering any ill effects.
