Oscar nominee Jesse Eisenberg (The Social Network), Oscar winner Melissa Leo (The Fighter), and 30 Rock star Tracy Morgan have reportedly signed on to star in the indie comedy Predisposed. According to Vulture, the trio will play a Julliard-hopeful, his drug-addicted mother, and said mother’s drug dealer, Sprinkles, respectively. Predisposed will be directed by Oscar nominated scribe/co-writer Ron Nyswaner (Philadelphia) with Philip Dorling sharing co-writing credit as well. Briefly, the comedy will center on the dysfunctional relationship between Eisenberg and Leo’s mother and son pair. The story is set on a day in which the son is interviewing for Julliard while his mother is busy feuding with her drug-dealer/checking herself into rehab while intoxicated so as to overcome her lack of health insurance.

Leo should be well prepared for her role as Eisenberg’s junkie mom as she made the same turn when Predisposed screened at the 2009 Sundance Film Festival as a short directed by the aforementioned Philip Dorling. Shooting on this promising feature length version of Predisposed is set to begin this summer.
