Continuity mistake: When the movie first begins, Jan is talking to radio talk show host Howie Carr, if you look really carefully at one of the shots, Howie has a pen in his hand that he is holding steady. In the next shot, he is twirling the pen in his hand. The next shot shows the pen steady again.
Continuity mistake: When Jan races his Porsche to meet with the families for the first time, he speeds along a distinctive stretch of road towards Woburn. In the next scene, he is getting a speeding ticket while stopped on a bridge. After his meeting with the families, when he leaves racing away from Woburn, he speeds along the SAME stretch of road, only to be stopped again on the SAME bridge. The bridge should have been behind him as he reached that stretch of road leaving Woburn, not ahead of him. (00:09:10 - 00:11:30)djm
Factual error: The box car shown by the leather faculty has the reporting marks SCRF which is a south Carolina railroad. This takes place in Massachusetts.
