Factual error: When Nick, Kurt, and Dale are in Rex's closet, Dale appears to be turning on the gas. What he is turning is actually the screw to secure the regulator onto the gas cylinder. You can see the valve to release the gas at the top end of the cylinder. (00:46:30)
Continuity mistake: The second time the 3 dudes talk to the black guy in bar, the black guy is first wearing the watch from Nick, which then disappears. (01:07:00)
Continuity mistake: When the guys are brainstorming ideas, and Dale writes "Murder" on the board, the writing changes between shots.
Continuity mistake: When Julia is entering her office building she is wearing a black skirt and pantyhose. When she is inside opening the office door for her sex addiction group she is wearing black leather pants under the skirt. Then a few shots later she has pantyhose on again.
Continuity mistake: After the boys kidnap Rex Hanson and Rex proposes that they join forces to escalate the caper, Rex repeatedly bangs his own face into a desktop, resulting in a prominent bruise on his right cheek. Over the next several scenes, Rex's bruise changes shades several times, from dark red to faint brown and back to red, and then vanishes entirely, all within the course of one day.
