Exclusive: Listen To Brie Larson Sing "Big Rock Candy Mountain" From 'Room' Plus First Clip From The Film

This fall, no movie will give you as well-deserved or satisfying a big cry as Lenny Abrahamson's "Room." Based on the novel by Emma Donoghue, and starring Brie Larson, the movie is already earning a lot of awards season talk following positive receptions at both Telluride and TIFF, and today we have an exclusive that will tug at the heartstrings.

The moving drama tells the story of a young woman who cares for the young child she has given birth to while held in captivity for years. The small shed in which they live is the only world her son has ever known, but when a chance to escape presents itself, Ma sets in motion a chain of events that will change her life, and that of her son Jack's, forever. Below, you can hear Larson sing the traditional folk song "Big Rock Candy Mountain" to Jacob Tremblay, who plays the child in the film.

"Room" opens in select cinemas this weekend, and nationwide on November 6th. The soundtrack will be available digitally...
