Los Angeles-based Occupant Films has cast Ben Kingsley, Josh Peck, Famke Janssen, Mary Kate Olsen, Olivia Thirlby and Method Man in its upcoming comedy The Wackness.

Jonathan Levine, whose debut feature All The Boys Love Mandy Lane was Occupant Films' hit maiden launch at Toronto 2006 and will now be released through Senator US in early 2008, recently began principal photography in New York.

Occupant Films partners Keith Calder, Felipe Marino and Joe Neurauter will produce the film, based on Levine's screenplay about a teenage drug dealer who forms a dangerous liaison with the daughter of his drug addled therapist.

Kingsley starred in this summer's independent release You Kill Me and will next be seen in The Last Legion. Janssen currently stars in the ensemble comedy The Ten.

Peck previously starred in Mean Creek and the hit Nickelodeon TV series Drake And Josh. Thirlby was part of the ensemble in United 93 and will next be seen in Juno, Snow Angels and Margaret.

Method Mad is best known for his roles in How High, Garden State, and Gone In Sixty Seconds. Olsen returns to the big screen in a significant role for the first time since 2004's New York Minute.

Occupant is currently in post-production on its second film, Peter Himmelstein's The Key Man starring Jack Davenport, Hugo Weaving, Brian Cox and Judy Greer.

Levine and Olsen are represented by UTA, Kingsley and Janssen by CAA, Peck and Method Man by ICM, and Thirlby by The Gersh Agency.
