Brie Larson's adorable message to Room co-star: 'Thank you Room for bringing us together'

Brie Larson has written a heartfelt note to her Room co-star Jacob Tremblay.

The actors starred together as mother and son in the critically lauded indie drama directed by Irishman Lenny Abrahamson.

Oscar winner Brie took to Instagram to share an adorable photo of the pair sharing a toast at the Telluride Film Festival premiere of Room, which was an Irish produced movie and written by acclaimed Irish author Emma O’Donoghue.

28 weeks ago(according to Instagram) @roomthemovie premiered at the #telluridefilmfestival. After the screening @jacobtremblay and I toasted. He had chocolate milk and I had red wine. I remember feeling so vulnerable after sharing this movie with the world for the first time; unsure of what was to come. Last night marked what may be our final toast to this film . He had a soda and I had sake. We are in Japan. Together we have traveled the globe, spent almost two years hanging out, playfully arguing about things like who can hold their breath longer and talking at length about Room. At its core, every step of the way has been taken with love. We were generous and patient with each other. We laughed a lot, especially when it was hard. We picked each other up, answered for the other when one was tired and always kept silliness alive. Thank you Room for bringing us together. Thank you Room for uniting us with the rest of the world. Thank you to everyone who shared this journey with us. I will never ever forget it.
