Room is an emotional and suspensful film that is equal parts uplifting and terrifying. At its core it's about a mother, who despite a seemingly impossible situation, just wants to give her son a fulfilling life. To bring this story to life on screen in a way that is believable in how it takes the audience through an emotional spectrum that ranges from despair to euphoria, took an extremely talented and dedicated cast and crew.

In this Fandango Movieclips featurette, you'll see how this amazing cast, which includes Brie Larson, who truly embodied the psychological nuances of "Ma," a single mother protecting her child, Jack, played with remarkable depth by Jacob Tremblay. Director Lenny Abrahamson and screenwriter/auther Emma Donoghue both speak to the complexities the cast faced in telling this story. Larson and fellow cast member Joan Allen also talk about how they were able to work together to tell this gripping story.

Room is in theaters now.
