Revealing mistake: When Jackie shoots her brother's left ear, there is a hole punched into the wall, behind him. We should be able to see into the hole, but we can't because the angle of the hole into the wallboard is wrong. From where Jackie took her shot, the bullet should be angled similarly to the (extra bright) light and the camera angle (our POV), but, instead, it goes perpendicularly into the wallboard. (00:35:20)
Revealing mistake: When Foxy and Claudia get into a brawl at the cocktail lounge, a character named Jackie comes the defense of Bobby (knocked out with a bar stool). When Jackie is knocked into the jukebox by Claudia, you can see the padding around her midsection under her sweater, protection from the "break-away" barstool used by Claudia to defend Foxy.
