EXCLUSIVE: The indie film 5 To 7, which surfaced when Star Trek‘s Anton Yelchin signed to star, just got a major cast infusion. Glenn Close, Frank Langella, Skyfall‘s Bérénice Marlohe, Lambert Wilson and Olivia Thirlby have joined the cast of a film that is a co-production between Mockingbird Pictures and Demarest Films. Mad Men writer Victor Levin is directing the film, which starts shooting next month in New York. In the romantic comedy, Yelchin plays an aspiring novelist who has an extramarital affair with the beautiful wife (Marlohe) of a French diplomat. Cultures, world views, personal ethics and dietary preferences clash as love deepens. The pic is being produced and co-financed by Sam Englebardt and William D. Johnson of Demarest Films, and by Bonnie Curtis and Julie Lynn of Mockingbird Pictures with their investor group as executive producers. The film is co-executive produced by Lisa Wilson and Myles Nestel of The Solution Entertainment Group, which is handling international sales and will represent the film at the Cannes Film Market. CAA and WME are co-representing the U.S. rights.
