Robert Downey Jr. In 'Cowboys & Aliens' Talks

Cowboys and Aliens
Robert Downey Jr. is in negotiations to star in DreamWorks/Universal's "Cowboys & Aliens," a pulpy mix of the sci-fi and Western genres that could serve as a potential 2010 tentpole.

"Cowboys & Aliens" derives from a graphic novel written by Fred Van Lente and Andrew Foley from an original idea by Rosenberg. The story centers on an Old West battle between the Apache and Western settlers, including a former Union Army gunslinger named Zeke Jackson (Downey), that is interrupted by a spaceship crashing into the prairie near Silver City, Ariz.
