Who copied who?

How interesting! Of course, the Spanish movie is less known. Sometimes there are coincidences. I need to watch the Spanish one first, though...

The short story is called "Moth" by British author Rose Tremain. It's set in an American trailer park and the narrator is a character not in the film, a woman neighbor who sometimes cares for the daughter. The film makes Ricky's parents a lot more sympathetic than in the short story. "Moth" can be found in Rose Tremain's short story collection, "The Darkness of Wallis Simpson."

While I was watching the credits of "Ricky", I did see Moth and Rose Tremain listed in the credits toward the end.
