VIDEO Emotional trailer for Lenny Abrahamson's Room

What Richard Did and Frank director Lenny Abrahamson is back with a new movie called Room. It's based on a book by Irish author Emma Donoghue and tells the story of a mother and son living in a tiny home in mysterious circumstances.

Here's the newest trailer.

The film recently debuted to rave reviews at the Telerude Film Festival in Colorado and it will also be appearing at TIFF and the BFI London Film Fest. Author Donoghue worked on the script from her own novel which was nominated for a booker prize on its release in 2010. It is all told from the perspective of the young boy Jack, something which must have presented a real challenge for the adaptation.

Room stars Brie Larson, Joan Allen, William H Macy and Jacob Tremblay as Jack. The film will be on general release in the US in October 2015 and in Ireland in January 2016.
