Julianne Moore is set to join the cast of Joseph Gordon-Levitt's feature film directorial debut.
The 'Game Change' actress is in negotiations to play the unlikely mentor to a modern day Don Juan (played by Joseph) who is on a mission to become less of a "selfish d**k", with Scarlett Johansson previously confirmed as a love interest.
Joseph has also written the script and has said this is the first time he was happy enough with his writing to turn it into a feature film.
He said: "This is the first time I finished a feature film I thought was good enough to make into a movie. I’ve written others, including one mammothy huge sprawling thing that encompasses my entire point of view of everything since I was 20 years old. Those efforts are in a drawer somewhere.
"I wrote myself a helluva role, one that people wouldn’t necessarily thought of me for."
Nicolas Chartier's Voltage Pictures will finance the film while Ram Bergman will produce through his Ram Bergman Productions.
Shooting on the untitled film is expected to begin next month.
