The movie is about a horse trainer how's best horse gets killed and its cattled is stolen. The horse trainer finds a wild black horse and tries to tame it. Its and old movie, I don't remember much about it, I hope someone can help me

It's not black beauty nor national velvet

Its not a recent movie, it must be from 1970's, 1980's or 1990's

It's probably the Black Stallion. It's a book too.
