The “Foxcatcher” actress edged out Jaimie Alexander (“Thor”) for the coveted role

In a competitive situation, Sienna Miller has emerged with the female lead opposite Bradley Cooper in Clint Eastwood‘s “American Sniper,” an individual familiar with the Warner Bros. project told TheWrap.

Warner Bros. had no comment, while Miller’s representatives did not immediately respond to requests for comment.

Cooper stars as Chris Kyle, a Navy SEAL who has the most confirmed sniper kills in U.S. military history. Miller is in early talks to accept an offer to play Kyle’s wife, who must raise his children while he’s overseas fighting the enemy.

Eastwood has spent the past week deciding between Miller and Jaimie Alexander, who plays Lady Sif in the “Thor” movies. Kate Mara was an early contender for the role, but her casting in “Fantastic Four” took her out of the running. Back when Steven Spielberg was attached to direct, Evangeline Lilly was rumored as the frontrunner for the coveted role, but she’s expected to spend the spring filming Marvel’s “Ant-Man” with Paul Rudd.

Jason Hall wrote “American Sniper,” which is scheduled to start production next month. Cooper is producing through his 22nd and Indiana banner along with Andrew Lazar and Peter Morgan.
