"War Horse" was just a poor story. In WWI, when presented with THAT quality of horseflesh, a German Officer would have taken and ridden both of those horses until and unless someone shot the horse out from under him. They were both too well bred to be used as driving horses, for that purpose. They lost me at that point of the movie. Then they tortured me when the horse ran through 3 barbed wire fences and survived. I think we've had some threads here about barbed wire accidents--ask THOSE folks if they thought this was credible.
Regarding "Secretariat," I recently watched a doc with Penny Chenery. She said that for a few months after relocation at Claiborne--bc of the stud syndication agreement--Secretariat recognized her when she came to visit. After that, she was just another human walking through the stables. THAT's food for thought.
"Seabiscuit" was written about 3 humans and one horse, and how they changed each other's lives. You should read the book--it's excellent.
I read about an English officer who purchased several injured Cavalry horses after he (and they) survived the Battle of Waterloo. He relocated them to his estate, and when they had recovered, he often observed them rallying at the top of the hill, just like they did in battle,and "dressing" in line. Remarkable what you can train a horse to do and what they remember.
WHY couldn't the author of "National Velvet", let Velvet stay on the "Pi" and win the race?!?!?!? Won't watch it--STUPID ending.
I am a non-fiction reader and I have a hard time enjoying somebody's fanciful, fictional, horse movie.
