Justin Bartha has joined Catherine Zeta-Jones in The Film Department's upcoming romantic comedy The Rebound, written and to be directed by Bart Freundlich.

The Film Department is financing and producing the film, which is set to start production on April 21 in New York.

Tim Perell, Freundlich, Mark Gill and Robert Katz are producing, with Neil Sacker and Michael Goguen serving as executive producers.

The Process production centres on a relationship that develops between a 25-year-old New York resident and the sexy single mother who lives in his apartment.

Bartha recently reprised his role as Nicolas Cage's sidekick in National Treasure 2. His credits include Failure To Launch and Freundlich's most recent film, Trust The Man.

The Film Department International, led by newly appointed president Steve Bickel, will commence pre-sales on the title in Cannes next month. Bickel's roster includes the thriller Law Abiding Citizen starring Gerard Butler and scheduled to start production in August.

The Film Department fully finances and produces six films a year budgeted in the $15-55m range.
