Scenes are shot out of order, actors may remove jewelry or loosen their tie between takes, crew members accidentally get into the shot, etc. It's a miracle that a seamless film is released at all, especially concerning films with lots of makeup or special effects. It's not just older or low-budget flicks that gaffe, either. These slips include recent releases and big-budget movies. All it takes is a second for something to move out of place.
Some slips are obvious, like a boom mike diving into the scene or a sudden costume change.
Others are more subtle - bad plot logic, anachronisms, etc. This page has 'em all. True, some of these things seem more like nitpicking, but we are slip- spotters, and we know one when we see one. The following are all slip-ups that I've found, unless otherwise noted. I hope you enjoy them.
