What were the names of john horses by movie?

It seems you're asking about the names of horses belonging to the character "John" in movies. However, it's impossible to give you a definitive list without knowing which specific movie you're referring to.

To help me understand your request, please specify the following:

* Which movie are you interested in?

* Is "John" the name of a character in the movie? If so, what is his full name?

* What is the movie's genre? This can help me narrow down potential horse names.

Once you provide me with this information, I can try to find the name of the horse(s) owned by the character "John" in that specific movie.
