I saw a movie about a girl and a horse once.
You're undoubtedly talking about National Velvet (1944) starring a young Elizabeth Taylor, Mickey Rooney and Angela Lansbury.
I surfed in Sierra Leone a few years ago and some of the locals were so poor they had to eat rotten horse meat from a carcass that sat by the side of the road the entire time I was there. What's even funnier is that I was staying with a really rich family and we used to throw out much higher quality leftovers everyday. Hahahahahaha, funny stuff.
