Continuity mistake: When D-Fens attacks the Oriental shopkeeper he puts his foot on the shopkeeper's neck and his socks are clearly visible as white. However, a few minutes later when he removes his shoe to examine a hole in it on the hill, before being confronted by the two homeboys - his socks have somehow changed to black. (00:10:20 - 00:18:15)
Audio problem: Near the start of the movie, D-Fens calls his ex-wife at her house. When she enters the kitchen, the phone isn't particularly loud, yet in the previous shot, she was quite far away from the house, with lots of people chatting and making noise, there's no way she could have heard it at the point she did.
Visible crew/equipment: After D-Fens has crossed the golf course and climbed into the garden with the family barbecue, he slumps against a wall as he talks to the family. We get a close-up of D-Fens for a good 30 seconds or so, and during this time the camera lens is very clearly visible as a reflection in D-Fens' glasses. (01:26:40 - 01:28:10)
Continuity mistake: When D-Fens meets with the two gang members, watch the gangsters positions as they stop walking. They are standing close to each other as one of them says, "I'm not laughing." The other says, "I'm not either," and they are suddenly standing about six feet apart from each other in the next shot, even though the dialogue overlaps the shots. (00:18:30)
Continuity mistake: When Douglas is watching the video of his wife and kid on the pier her eye make-up is running through her tears of fear. It cuts back to Douglas then back to her, the make-up has gone. It would be hard for her to wipe her eye as she is holding the girl with both hands. (01:35:35)
Continuity mistake: After the struggle between D-Fens and the Korean store owner, a box of raisin bran and a box of maxi-pads can be seen lined up on the bottom shelf. D-Fens then whacks the shelf with the baseball bat, causing the two boxes to become angled and askew. The store owner says, "Take the money." and in the next shot the boxes are properly lined up again. (00:10:10)
