“I only do serious films now.”

So Sarah Silverman jokingly told ET at the premiere of her new movie, the drama I Smile Back. Silverman plays a mother-of-two living in suburbia and struggling with depression and various addictions. It’s a departure from the Silverman most of us know onscreen, to say the least.

“The sequel’s going to be really funny,” she said with a laugh.

Even though the movie may be “very depressing,” as Silverman puts it, she was all smiles walking the red carpet at ArcLight Hollywood. “I've got all my buddies here. I can't wait to see them and squeeze them,” she beamed. “I've got a lot of comics coming to see this very depressing movie.”

The movie, aside from showcasing a different side of the comedian, has also allowed her to be open about her own depression. “People really appreciated it,” she said of the response she’s received. “It’s so odd that it is not as common that people just talk about. It's okay…It's a real thing. It's just called being human.”

All joking aside, we probably will see the actress tackle more "serious" roles in the future, as she’s already getting awards buzz for her powerful performance. “I’m letting it make me feel very nice,” she said of the glowing reviews.

“I try not to have it be what creates my self-esteem,” she continued. “Because I’m working hard in therapy to have that come from inside and the pendulum swings both ways.”

I Smile Back opens in theaters on Oct. 23. Watch the trailer now:
