Continuity mistake: When Red is sitting at the toilet after he's been shot, there's a bowl of noodles on the toilet seat.

Continuity mistake: During the chase scenes, the driver side window of the car that Dale and Saul are in is rolled up. When Saul slams on the brakes during the chase, the lady cop shoots out the passenger side window of the car on her first shot. Her second shot obviously goes over Saul's head, but it doesn't shoot out the driver side window. The window is still intact when they abandon the car.
Continuity mistake: During the chase scene, the police car they are riding in loses a hubcap, but in the next shot it's back on, then it's off again.
