Continuity mistake: In the beginning when Eric is taking the shoe print off the car door, you see him removing the silver sticky paper from the door first, then you see him starting the process when they start with the slide show of him collecting the evidence.
Visible crew/equipment: In the flashback of the murderer slamming the car door on the victim's neck and breaking it, we get a clear shot of the cameraman and his camera in the car door (CSI's favorite blooper).
Continuity mistake: Episode "Just Murdered": When Horatio confronts the couple at the bank after the safe deposit box is opened, you can see that the wife has her earrings on. When they flash back to that scene later in the movie, she doesn't have them on. She shouldn't have them on since she hasn't gone to the lawyer and retrevied them yet. She shouldn't have them in the first scene.
Visible crew/equipment: When Horatio and Eric are talking in the CSI building corridor, notice the reflection of the overhead microphone on the left side mirror.
Plot hole: The pool boy's lawyer brings in the woman suing Fell and tells the judge that Sells saw her earlier and didn't recognize her when he should have. There is absolutely no way she could have known that.
Answer: Yes, sizes of jails differ.
