Sierra/Affinity has sold out worldwide on Demolition, the romantic drama from Dallas Buyers Club helmer Jean-Marc Vallee starring Jake Gyllenhaal and Naomi Watts. Gyllenhaal plays an investment banker rallying to rebuild his life after a family crisis with the help of a struggling mother and her unusual son. Fox Searchlight is readying a 2015 domestic debut.

Back in September, Sierra/Affinity took the pic co-financed by Black Label Media, Sidney Kimmel Entertainment and Fox Searchlight Pictures out to international buyers at Toronto; the company closed out final territories at AFM last month. The project, based on a Black List script by Bryan Sipe, also stars Chris Cooper. It was produced by Black Label Media’s Molly Smith and Trent Luckinbill, Sidney Kimmel and Mr. Mudd’s Lianne Halfon and Russell Smith. Thad Luckinbill, Right of Way’s Jason Reitman and Helen Estabrook, John Malkovich, Ellen Schwartz, SKE’s Carla Hacken, and Nathan Ross are exec producers.

Fox Searchlight is plotting a 2015 release in the U.S. and also is distributing in the UK, France, Germany and Australia/New Zealand. Sony has Latin America, Eastern Europe, Scandinavia, Iceland, and Greece, while deals have been inked for Benelux (Remain in Light), Canada (VVS Films), Hong Kong (Lark), India (PVR), Israel (United King), Italy (Good Films), Japan (Phantom), the Middle East (Eagle Films), Portugal (Lusomundo), South Africa (Ster Kinekor), South Korea (Main Title), Taiwan (Filmware), Thailand and Vietnam (IPA), and Turkey (Fabula). CAA brokered the domestic deal.
