Deliberate mistake: When Shorty is showing Cindy some moves and they are doing the "Right, left, right, left" move, you can see three people walking right behind them. Then, suddenly, the people are gone without the scene being cut. The director has simply just overlapped the scenes while they are doing the moves.
Continuity mistake: When it shows Dwight and Theo together, Dwight goes to the stairs, and starts to climb up on his own, and Theo covers him. In one shot, as it shows Theo holding her gun out, there is a clock by her, and the time is 9:10. But when the shot changes, and Theo asks Dwight "Do you need help" the time has changed to 9:45
Continuity mistake: When Cindy rubs Buddy in the cold chamber, in one shot Cindy says "...and you're gonna have lots of little babies..." and behind Buddy's head, a black towel can be seen. It isn't there is any of the following shots, and wasn't there in any of the previous shots either.
Continuity mistake: When the character played by Kathereen Robertson walks into the dining room and asks the guys to get her a seat, Buddy places a seat right in front of her yet in the next scene, two chairs slide up to her followed by a wheelchair and Buddy seems to have teleported into a different room altogether.
