EXCLUSIVE: Broad Green Pictures scooped up rights to I Smile Back in March after the film premiered at Sundance, sparking right away to Sarah Silverman in a rare dramatic turn. In this exclusive trailer ahead of its Saturday festival premiere, you can see what the fuss is about: Silverman plays Laney, a suburban mom who seemingly has everything but suffers from depression which launches her, both internally and outwardly, to dangerous places, threatening herself and those she loves. The pic is a Special Presentation at TIFF, and screens first for press and industry Saturday before its Canadian premiere Wednesday night at Princess of Wales.

Adam Salky directed the drama, which co-stars Josh Charles as Laney’s husband, Thomas Sadoski, Mia Barron, Terry Kinney and Chris Sarandon. It’s based on the Amy Koppelman novel that she co-adapted with Paige Dylan. Brian Koppelman produced with David Levien, Mike Harrop and Richard Arlook. Skip Klintworth is exec producer with Oscar Crosby Films and Jens Meurer and Christian Angermayer with Film House Germany.

Broad Green is releasing the pic domestically October 23. In the meantime, check out the trailer above.
