The trailer for I Smile Back promises something special from star Sarah Silverman, who portrays a wife and mother battling depression and substance abuse. The rave critical reviews that appear on screen call her performance “revelatory” and “monstrous,” and her intensity in the trailer gives credence to such praise. Whether she’s putting on a faux happy face for her kids or crumpling onto the floor under the weight of suburban malaise, the portrayal is leagues away from the buoyant comedic performances that made Silverman famous. Now it comes down to whether the film itself is worthy of Silverman’s hard work.

I Smile Back is set for release on October 23.
