Paul Schrader has written the same type of character repeatedly for years and and consciously thinks of them as variations ofnthr same character and increasingly thr films are intentional companion pieces.

Most recently with the Card Counter. Earlier films you might enjoy include Light Sleeper, Walker, and American Giggolo. He also has an upcoming film called thr Master Gsrdener which premiered but hasn't been distributed yet.

For some other recent riffs on this kind of thing, you might want to check out You Were Never Really Here and Saint Maude.
