Seimetz 's performance in '' A Horrible Way to Die '' won her the Best Actress award at Fantastic Fest . The film premiered at the Toronto International Film Festival to good reviews . She appeared in '' The Off Hours '' . About her , '' The Los Angeles Times '' wrote : " Every year , the Sundance Film Festival has a semi-official ' it girl ' who encapsulates the festival 's cocktail of discovery and buzz . But what about someone who embodies the independent film world 's sense of community and the pitch-in spirit of collaboration , something like a most valuable player ? That prize might well go to Amy Seimetz . " '' The Hollywood Reporter '' singled Seimetz out as one of the breakouts of Sundance that year : " As a late-night truck-stop waitress and orphaned lost soul , Seimetz invests Off Hours ' dead-end world of tiny tragedies with a hidden , hard-won strength . " She appeared in '' Revenge for Jolly ! '' . In 2012 , she made her feature directorial debut with the Florida-based thriller '' Sun Do n't Shine '' , which she also wrote , produced , and co-edited . The film premiered at South By Southwest to rave reviews . Indiewire wrote : " Her terrific directorial debut was a brilliant noir exercise with less mumbling than raw brawls . She pinned me to my Alamo Drafthouse seat and the film kept me there for the next 82 minutes . " Seimetz is the star of '' Upstream Color '' and '' Pit Stop '' , both of which premiered at the 2013 Sundance Film Festival . In February , she was added as a series regular to AMC 's series '' The Killing '' . In season 3 , she plays Danette Leeds , a " hard-living , financially strapped single mother whose 14-year-old daughter goes missing "
