The Wedding of Iron Man - S1-E13
Continuity mistake: When Tony and Julia are thrown from the car, they are shown landing on rocky terrain. When the shot changes, they are now shown to have landed in a grassy area, with Tony Stark lying face down with his head near a rock. When the shot changes again, Tony's head is now facing his right shoulder, and there is no longer a rock near his head. (00:17:00)
