His racy comedy, originally called "Don Jon's Addiction," has been streamlined to just "Don Jon."
Outside its screening at the South by Southwest film festival Monday night, Gordon-Levitt said he altered the name because some people mistakenly believed the film is about sex or porn addiction.
"I called it `Don Jon's Addiction' because there's this central symbol in the movie of this rut and this habit that Jon is in," said Gordon-Levitt, who also stars in the film. "It's about a guy getting out of this rut, learning to be present and have more engaged and realistic relationships."
It's the story of a modern-day Don Juan, a New Jersey lady's man who prefers porn to actual sex – even though he's having no shortage of the real thing.
