Katie Aselton stars as “Amy Haller,” David’s older sister who saw firsthand the toll a mental illness such as his can take on a family, on parents and on a marriage. Amy wonders, when she has time for such thoughts, if her pessimism and aversion to risk are a result of her childhood or if she comes by it naturally.

Aselton is an acclaimed actor and filmmaker who is best known for her starring role as “Jenny” in the FXX comedy The League. She can next be seen in the Warner Bros. comedy Bastards alongside Owen Wilson and J.K. Simmons, set for release in late 2017.

Aselton’s breakout acting role was in The Puffy Chair, directed by Mark and Jay Duplass, which was nominated for two Independent Spirit Awards. She made her directorial debut and also starred in The Freebie, which premiered to critical acclaim at the 2010 Sundance Film Festival and was released theatrically by Phase 4 in 2010. She also directed and starred in the survivor thriller Black Rock alongside Lake Bell and Kate Bosworth, which premiered at the 2012 Sundance Film Festival and opened May 2013.

Other television credits include HBO’s Animals, HBO’s Togetherness and Hulu’s Casual.

Audiences also saw Aselton in the Jesse Peretz comedy Our Idiot Brother opposite Paul Rudd. Additional credits include Intervention, which premiered at Berlin Film Festival in 2006; Cyrus, which debuted at Sundance in 2012; and Kyle Patrick Alvarez’s Easier with Practice.
