Rebecca Mader joins 'Goats' herd

Joins George Clooney, Ewan McGregor in cast

Rebecca Mader, best known for playing scheming redhead Charlotte on ABC's "Lost," is in final negotiations for the lead female role in "Men Who Stare at Goats," the George Clooney- and Grant Heslov-produced adaptation of the book by Jon Ronson. Heslov is directing.

"Goats" 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 (Clooney), who claims to be a former secret U.S. military psychic soldier who was reactivated after 9/11.

Mader will play McGregor's wife.

Stephen Lang, who appears in James Cameron's "Avatar" and Michael Mann's "Public Enemies," also joins the cast that includes Kevin Spacey and Jeff Bridges, playing an intelligence officer.

Mader and Lang are repped by Innovative.
