Continuity mistake: When Jackie leaves the bag in the dressing room for Max, it's on the middle cushion of three. However, when Max looks into the room, the bag is on the left cushion. (01:47:00 - 01:57:19)
Factual error: When Max returns to get his gun from Jackie, she invites him in for a cup of coffee. She puts on a Delfonics record, which starts with the song "Didn't I Blow Your Mind." It then goes to the song "La La Means I Love You." She doesn't touch the record once it starts playing. There was not a Delfonics record pressed that has those two songs together in that order.
Factual error: Ordell's house is set in Hermosa Beach. In the scenes that you can see out of his living room window, there is the beach, and a bike path approximately halfway between the house and the ocean. The bike path in the movie is a good distance from the house, but in actuality the Hermosa Beach bike path is right in front of the houses. There is also a rock formation seen outside of the window, which is not in Hermosa Beach either.
Character mistake: Near the end of the movie when Ray shoots Odell, Ray checks Odell's pulse using his thumb. Since the thumb has an artery in it, you should never check someone's pulse using your thumb. As a cop, he should know this because I'm sure he's taken basic first aid.
