Room was an intense viewing experience. But I'll admit that, when your character, Ma, reenters the world and visits her old bedroom, my attention went to the decorations. Were the pink walls and boy band posters true to your own life?
Ethan Tobman was our production designer. He's a genius. I spent so much time with him. We were just talking about that, actually. He said, "The room was the hardest set I had to build." And I said, "Yeah, makes sense." You know? That's the whole movie. And he's like, "Oh no, not that room -- Ma's bedroom." I was like, "Wait a second. That's just not possible. How is that possible?" [But] in one shot, in one frame, you have to understand an entire life of somebody. It's the only way we really get to know her. It's the only explanation we have of her.
What was in her bedroom?
Tons of stuff. [For posters], I was just like constantly emailing him with the music that I was listening to at that age. I also found my old iPod -- like my old, huge iPod from when I was 15 -- and gave it to him, so he would listen to it while he was decorating the bedroom.
Now you have to admit what was on 15-year-old Brie's iPod.
It's so all over the place. It's like, Rolling Stones -- like bad Rolling Stones remixes mixed with like, Aaliyah and like Big Star. And the Zombies. Like a combination of all sorts of things. I'm sure there was Spice Girls on there as well. I don't want to make myself sound like I had great music taste at 15 because I'm not sure that I did.
No one did.
I did make a collage in my bedroom at 15 like the collage on the wall. I gave Ethan photos and he actually found specific things that were in my bedroom and put them in -- but I didn't know. I was just constantly sending him ideas and references and I let him arrange it all, and I didn't want to see any of it until we shot it.
What was in your collage?
Things that I liked in magazines. It could have been a picture of a hamburger, it could have been a shoe. It could have been a lipstick. It was just things that I thought were cool. I hung out in my bedroom as a teenager and collaged.
