Continuity mistake: There is a scene where everyone is dancing. It's towards the end but not at the very end. One of the employees of the record store takes his shirt off.

The escaped one gets out through the roof into an evening's sky. There's still light visible, but for a visit that lasts all of 4 minutes, it's far too quick a change. (00:23:00)

Before Richard gets back to the car however there is a shot of the door all dented up but in place. When Richard pulls the door off it falls to the ground and there isn't a single dent on it. (Also, is it me or does it seem a little ridiculous that someone that loves his car so much didn't notice the large dent down the edge of the door as he faced it while walking from the station to the car?)
