Rebecca Mader (ABC's "Lost") is in final negotiations to play the lead female role in the Grant Heslov-directed "Men Who Stare at Goats" says The Hollywood Reporter.

An adaptation of the book by Jon Ronson, the story is set in Iraq and centers on Bob Wilton (Ewan McGregor), a desperate reporter who stumbles upon the story of a lifetime when he meets Lyn Cassady (George Clooney).

Cassidy claims to be a former secret U.S. military psychic soldier who was reactivated after 9/11. Mader will play McGregor's wife.

Kevin Spacey, Jeff Bridges, and Stephen Lang are also part of the cast. Clooney also produces alongside Heslov.
