Zero Dark Thirty star Joel Edgerton is in negotiations to join the cast of Jane Got a Gun for director Lynne Ramsay (We Need to Talk About Kevin).

The story follows Jane Hammond (Natalie Portman), a woman in the Old West who enlists the help of a former lover (Michael Fassbender) when a band of outlaws come searching for her husband. Joel Edgerton will play John Bishop, the villainous leader of this evil group.

Lynne Ramsay will direct from a screenplay by Brian Duffield, which landed on the 2011 Black List. We reported in May that the project may be funded through a combination of studios, private equity companies, and foreign pre-sales. It isn't known if financing has been fully secured yet, or when production may begin.
