Continuity: In the scene where Rick kills Ray and takes him to that warehouse, Rick stabs Ray in the back, yet when Rick carries Ray to the incinerator he is carrying him with Ray's back against his chest, but there is no blood on his clothes.

Factual error: During the custody hearing, the Maryland flag in the courtroom is upside down. The rule for a Maryland flag is "black and gold, top of the pole," this flag has the red symbol at the top.

Continuity: When Rick kills Ray it is raining out, but when he pulls into the warehouse his truck is completely dry.

Factual error: When Vince Vaughn is driving to pick up the guy at the motel with the kid in the back, you get a quick glimpse of a road sign. The road number is in a diamond, but Maryland state road numbers are in a square.

Continuity: When the mother finds her husband cleaning his burn wounds she goes to get her son, which is on the computer in his room. A second later, the boy is back in his room hiding from the husband and the computer is gone.

Factual error: The cop told Frank that no evidence was found of a body in the incinerator. However, even if the rest of Steve Buscemi's body had burned to dust, his teeth wouldn't have, as teeth are enamel and don't burn. They would've still been inside the incinerator long after the rest of the body had burned.

Continuity: The position of Susan's arms when she is in the interrogation room keeps changing instantly.

Continuity: When Vince Vaughn pulls the ice pick out of Steve Buscemi's back, there's no blood on it.

Plot hole: When the police bring the car in for a forensic search after the murder, you see the policeman open the passenger door and he is correctly wearing rubber gloves. However, the policeman driving the car into the garage is not. Surely he should also be wearing gloves and not adding his finger prints all over the car?

Continuity: When Rick, Ray and Danny are out on the sailboat Danny is sitting near the bow trailing his leg in the water. His Dad yells at him and as the shot changes to a more distant view of the sailboat, Danny is nowhere to be seen.

Continuity: Throughout the movie, the boy goes through a few hairstyles, and he goes back and forth from small and young looking, to taller and more mature looking.

Visible crew/equipment: In the scene where Vaughn hits Travolta over the head and is sprinkling the gasoline around you see one shot of Travolta on the floor. Just behind him you see someone walk by, you see only a leg with white trousers and brown boots.

Continuity: When Danny looks outside his room after someone tries to open his door, the light is on. He closes the door and then Rick threatens him. When Rick walks outside Danny's room, the light is off.

Plot hole: WARNING-SPOILER! Right after the climax, the paramedics show up to take Vince Vaughn away for being electrocuted and Teri Polo for being thrown against a wall and miscarrying her pregnancy. John Travolta has just been belted over the head with something at his boathouse and left for dead. Then he has the fight with Vince Vaughn where he gets belted in the head again with a paint can, gets kicked while he's down - then gets his head smashed through the passenger window of the SUV! And yet he is fine to drive off happily ever after - no medical attention required whatsoever.

Continuity: After Teri Polo is married to Vince Vaughn (after the ring and the kiss), they hug. You can distinctly see Teri's arms are under Vince's, but in the next shot, from the other side, her arms are over his.
