Room” has been a transformative experience for Brie Larson, winner for motion picture drama actress. Not only has the film boosted her name recognition and vaulted her into the ranks of awards contenders, but she also got to witness the impact that an emotional film can have on audiences.

The awareness came as a result of the festival and awards season circuit, a gauntlet often derided as trite and self-congratulatory. Larson found it anything but during the past eight months that she has lived with “Room.”

“Through talking about it I discovered the movie over and over again in different ways,” Larson said. “To find new meaning within this movie has been absolutely incredible. Being out in the world and seeing how a piece of art like this connects with people… it’s warm and welcoming, like having a friend wherever you go.”

During the filming process, Larson said she didn’t have the luxury of being “precious about my performance.” Her focus was on providing a comfortable and creatively nurturing environment for her 8-year-old costar Jacob Tremblay.

“It was always about him, making sure he felt happy and comfortable and a space he could be creative in. Watching him flourish every day — that was enough,” she said.

Larson was clearly moved by her win. And coming off a year when she did everything from the broad comedy of “Trainwreck” to the soul-bearing work in “Room,” it’s clear she’s spent some time thinking about the metaphysics of smoke and mirrors.

“The idea of someone sitting in a theater is very sacred to me,’ she said. “That’s how I learned about the world, that’s how I learned about different cultures… learned about being a woman; I believed every frame. I feel a deep sense of responsibility to be as vulnerable as possible, because vulnerability is the strongest thing you can ever do. They’re the way that we can process and make sense of this world and feel like we’re connected to it.”
