Continuity mistake: The person responsible for background shots while anyone is in a car driving, is grossly negligent in their continuity. Very rarely do Bones & Booth drive down a street without the background changing rapidly from urban to rural streets, and back. In a Season 1 episode, they're driving through a flat desert, with nothing in the background except scrub - and then suddenly, a mountain appears in the middle of the shot.
Revealing mistake: The producers have not taken enough generic shots of the places the gang hangs out at; the Royal Diner, & the Founding Fathers. If paying attention (or, watching multiple episodes in a row), one will notice the same people wandering down the street an awful lot! As well, outside the Royal Diner, there's a weird-shaped street corner, that appears to force all traffic in front of the Diner. This would be due to the size of backlot being limited, and certainly doesn't look right.
