Fox Searchlight has proven to be one of the most active distributors at the Sundance Film Festival by acquiring its fourth title, Another Earth.

Mike Cahill directed the drama from a script he co-wrote with star Brit Marling. The story centers on Brit Marling's character, an ambitious MIT astrophysics student who kills a man's family in a car accident after she leaned out of the car window to take a look at a newly-discovered planet. She spends four years in jail and then decides to visit the widowed husband and father.

Fox Searchlight acquired the project in a 24-hour auction immediately Another Earth's Monday night premiere. Focus Features and The Weinstein Company were also bidding on rights to the movie.

Another Earth marks the fourth acquisition for Fox Searchlight at Sundance, following Martha Marcy May Marlene, Homework and The Bengali Detective.
