Question for those who recorded this on TCM

I think there's a possibility the horse who played "Snowfire" was killed in the making of this film. Please review your recording of the fall from the cliff in the first five minutes of the movie. Note how the film is edited. First, there's a close shot of a real horse clambering over some rocks. He jumps out of the picture on the left. Then it cuts to a long shot of what appears to be a real horse, legs moving, falling down the cliff. There's a sudden cut to an obviously fake horse dummy seen from above falling into the water. Then a huge splash where you can't really see what fell. Then an edit to the ranch owner and ranch hands observing, then another cut to the horse swimming. I think the reason for the quick cut from the real horse in the long shot is that he started tumbling, striking the cliff wall, and died in the fall. I notice there's no indication that any animal welfare group participated in the filming of this movie. Also, I notice that this very talented horse appears to have no other film credits on his record. That would make sense if he died making this film.

What do you think?
