What is the movie called with boy that has a disorder causes him to have deformed face kind of looks like lion head and he girlfriend blind his mom was crazy?

The movie you're describing is likely "The Elephant Man" (1980).

Here's why:

* Deformed face: The main character, John Merrick, suffers from a severe disfigurement, often compared to an elephant due to his enlarged head and facial features.

* Girlfriend: Merrick develops a relationship with an actress named Mrs. Kendal.

* Blind mom: Merrick's mother is blind and possibly mentally unstable, though her role isn't central to the film.

Let me know if this is the movie you were thinking of!
