Best known for her role in David Fincher's "The Girl with the Dragon Tattoo," actress Rooney Mara made a striking enough impression in that role to earn herself a Best Actress nomination at the 2012 Oscars. Now highly sought after by Hollywood, her latest film is "Ain't Them Bodies Saints," a crime drama in which she stars as a young woman who goes on the run with her outlaw lover (Casey Affleck) in 1970s Texas.

Catching up with the young thesp at this weekend's Sundance Film Festival, where "Saints" made its big debut, HitFix spoke with Mara about what drew her to the project (the time period and the Texas landscape were two deciding factors, among other things), what it was like working with Affleck and directed David Lowery, and her thoughts on that supposed "Dragon Tattoo" sequel "The Girl Who Played With Fire."

The 2013 Sundance Film Festival runs from January 17-27 in Park City, Utah.
