Olivia Thirlby may be going mainstream. Best known for roles in indie flicks like Juno and The Wackness, Thirlby will star this week in effects-heavy alien invasion movie The Darkest Hour. Joining her is fellow indie notable Emile Hirsch, who plays the male lead. Despite the bigger-budget nature of the film, Darkest Hour looks like it’ll fly largely under the radar, with little buzz surrounding its upcoming release. Next year, Thirlby will appear in Dredd and Nobody Walks.
