According to The Hollywood Reporter, Ewan McGregor, Kevin Spacey, and Jeff Bridges are joining George Clooney, under Grant Heslov's direction.
The film is based on Jon Ronson's book of the same title, and follows his investigation into the secret wing of the U.S. First Earth Battalion, a paranormal research unit created in 1978. Its goal was to create "Warrior Monks," supersoldiers who could do all sorts of comic-booky things like walk through walls, become invisible, read minds, and kill creatures by staring at them long enough. One soldier in Ronson's book claims he killed a hamster and a goat doing just that.
Personally, I think I'd rather see Clooney in "Men's Room IV"...
I got the picture from Defamer.
