Indie-actress Olivia Thirlby (Juno) has locked down a role in producer Timur Bekmambetov sci-fi thriller The Darkest Hour. The Summit Entertainment/New Regency film marks Thirlby’s first commercial film since Universal’s 9/11 drama United 93.

Directed by Chris Gorak (Right at Your Door), The Darkest Hour follows a group of American students while in Moscow during an alien invasion. Thirlby will play a trust fund baby forced to work with others to survive the takeover.

Production on the film is set to roll in Moscow come summer.

In the meantime, Thirlby will shoot the teenage lesbian-werewolf thriller Jack & Diane with costar Juno Temple (Year One) in May.
