He has also revealed Joseph Gordon-Levitt has a part in a story entitled The Long, Bad Night. He will be a cocky gambler who doesn't have the best night, judging by the title.
Robert revealed to MTV that several portions of the film have been finished, with a dozen actors and actresses already done with their parts - a list that includes Jaime King, Jeremy Piven and Ray Liotta.

The film is currently slated for an October 2013 release.
