On Monday, Robert Downey Jr. dropped out of the adaptation of Scott Mitchell Rosenberg's comic book series "Cowboys & Aliens." But now Daniel Craig is in negotiations to replace him in the lead role of Zeke Jackson.
This would be his first collaboration with Jon Favreau, who is directing the film from a script by Roberto Orci, Alex Kurtzman ("Star Trek"), and Damon Lindelof ("Lost").
