The Skull in the Desert - S1-E17
Continuity mistake: During the scene when Booth and Bones are driving to tell Angela that her boyfriend is dead, the scenery behind Booth jumps suddenly mid shot. Initially the scene is of a wide plain, then suddenly a mountain range appears. This scene was obviously shot on a sound stage, with the scenic background being projected onto screens around the vehicle, an old trick in movie making. It seems that somebody mistimed the loop of the tape they were using. (00:12:30)
