Back in the beginning of February we learned that actor Joseph Gordon-Levitt was planning on making the jump to becoming a writer/director with an untitled comedy starring himself and Scarlett Johansson. The story was said to be about a modern day Don Juan trying to reform himself of such salacious behavior, and Johansson was attached to play one of two big female roles. A new report from Variety indicates that progress must be being made on the project, because not only is it scheduled to go in front of the cameras next month, but Gordon-Levitt has also landed another huge name to fill that second female role. Fresh off of turning heads with her creepily spot-on portrayal of Sarah Palin in the recent HBO-produced Game Change, Julianne Moore is said to have joined the project. Reportedly, she will be playing a character that becomes an unlikely mentor to Gordon-Levitt’s ladies’ man. Whether that mentoring is in the art of picking up the ladies or the art of no longer picking up the ladies isn’t quite clear, but either possibility sounds intriguing. As of yet, the film is still untitled. With cast in place and shooting set to begin, probably it’s time they get on that.
