Now that the fall festivals are unveiling their lineups, trailers are beginning to emerge for some of the buzziest titles that will also head into the awards season corridor. Room is one of them. The Lenny Abrahamson-helmed drama about a mother’s boundless love was acquired by A24 at Cannes 2014, and this year FilmNation sold out international on the Riviera where Universal took multiple key territories off of a promo. Today, we’re getting a first look at the captivity drama that’s based on the bestseller by Emma Donoghue. It’s got a Toronto Special Presentations slot and A24 just dated it for an October 16 platform release. We also wouldn’t be surprised to see this one play Telluride.

Brie Larson stars as Ma, a woman trapped with her son Jack (Jacob Tremblay) in a 10-foot by 10-foot shed that she calls Room. Therein, she’s created a whole universe for Jack and will stop at nothing to ensure that he can live a complete and fulfilling life — until it’s time to escape. Here we get a glimpse of life in and outside of Room and the new world that Jack will face. Joan Allen and William H. Macy co-star.

Room is an Element Pictures and No Trace Camping production, in association with Film4, Telefilm Canada, and the Irish Film Board.

Element’s Ed Guiney produced with David Gross. Executive producers are Andrew Lowe for Element and Jeff Arkuss and Jesse Shapira for No Trace Camping. Donoghue, Rose Garnett, Tessa Ross and Film4’s David Kosse also serve as executive producers.

Abrahamson last directed 2014’s quirky Sundance hit Frank with Michael Fassbender in a papier-mâché head. Larson’s profile has been rising recently. She’s headed for the female lead in Legendary Pictures’ Kong: Skull Island; co-stars in Trainwreck with Amy Schumer and Bill Hader; and just wrapped Ben Wheatley’s Free Fire, which is exec produced by Martin Scorsese.
