That's right Movie Pressers, Will Arnett and Revolutionary Road crazy/Oscar Nominee Michael Shannon have joined the cast of the Sam Mendes directed adaptation of Jonah Hex, starring Josh Brolin and co-starring John Malcovich and Megan Fox. Arnett will be playing a Union soldier named Lieutenant Grass who enlists Hex to kill Turnbull, Malkovich's Confederate voodoo practitioner. Grass is a man who's blindsided by the dirty fighting style of his enemies, a man more interested in new styles of warfare than really understanding his enemy.
Shannon will be playing Doc Cross Williams, the bizarre ringleader of a brutal gladiator / circus event. Williams' is one of Hex's recurring nemesis in the series, whose finest achievement is making Wild Bill Hickok into a zombie. The Hollywood Reporterstates he's likely to appear in sequels, which means Warner Bros. is actually thinking franchise, surprise surprise. What do you guys think?
