Joseph Gordon-Levitt will make his feature directing debut on an untitled comedy he’ll star in with Scarlett Johansson. Gordon-Levitt wrote the script, and Nicolas Chartier’s Voltage Pictures will finance the film and sell international rights in Berlin.

Ram Bergman is producing for Ram Bergman Productions in association with Gordon-Levitt’s hitRecord Films. Shooting will start April 16. While Gordon-Levitt would not give up too many details, I got this much: the film is a sexy comedy about about a modern-day Don Juan, and his quest to become less of a “selfish dick.”

He plays that character, and there is another female lead role that will be filled shortly. The move into the directing chair comes at a time when Gordon-Levitt is coming off the lead role as a cancer-stricken man in 50/50, and has both The Dark Knight Rises and Premium Rush set for release later this year.
