Continuity: When Sonora does her very first dive, we see Clifford release Lightning and he begins to trot up the ramp. In the next shot, the camera shows the front view of the horse, and he is cantering up the ramp. Then the camera goes back to Lightning's front view, and he is trotting again.

Continuity: At the beginning of the movie, when Sonora gets challenged to jump Lightning over the fence, she tears off a piece of her dress and ties it to Lightning's halter. There is no bit because she did not have one. But as Lightning begins to trot, there is now a bit in his mouth.
