A Menina E O Cavalo 1983 Portable -
Alternatively, maybe "a menina e o cavalo" is a local Brazilian film titled that way in 1983. Let me double-check. A quick search shows that "A Menina e o Cavalo" isn't a well-known Brazilian film from 1983. It's possible there's a mix-up in the title. Perhaps the user meant "The Man Who Shot Liberty Valance" (1962) which is "O Homem que Matou Liberty Valance" in Brazil, but that's not 1983. Alternatively, maybe they're referring to "The Horseman" (O Cavaleiro) from 1983, which is set in the American Wild West.
