Dead Ringer - S4-E20
Continuity mistake: When Nick is showing the burger guy the pictures from the ATM, he holds one up while facing the see-through window. He turns and puts it on the table and it's a completely different picture.

Audio problem: When Sarah is interrogating the police woman, there are some shots from the left side of the woman when she is speaking and her mouth/jaw movement do not match the words that she is saying.

Revealing mistake: At the beginning of the episode, when Grissom notices the body and pulls over, in the close up of him you can see that the steering wheel never moves: he just moves his hand to make it look like he's pulling over.
