Audio problem: When Jill comes home, takes off her shoes and leaves the living room, Jimmy runs after her shouting "Don't go in there, there is a surprise in there.". However as we see him come running into the room we can see he doesn't move his mouth at all. (00:03:35)
Continuity mistake: When Strabo is pointing his gun at Oz and Oz hits it with his flowers, a shot goes off. Then it shows a lamp being hit. A split second later the vase beside it also breaks. There shouldn't be a split second between the two items breaking. A gunshot at that range would make both the lamp and the vase break at the same time. (00:21:35)

Continuity mistake: When Lazlo's men begin to shoot inside Oz' house, Oz runs out. At the same time Lazlo turns on the light. Then we hear the engine on Oz' car start. It's impossible for Oz to have gotten to his car THAT fast. (00:21:40)
Continuity mistake: When Jill and Jimmy are arguing at the motel, Oz tells Strabo that Jimmy killed 21 people. Later at the bar when Jimmy is very drunk, he tells Oz that he has killed 21 people. Oz corrects him and says, "22 people", and Jimmy says, "Who'd I forget". Oz replies with "Frankie Figgs". Apparently Oz had forgotten that information as well when he was bragging to Strabo earlier.
