Alien Migration

Robert Downey Jr. is on target to appear in another film based on a comic book. A sci-fi/western "Cowboys and Aliens" according to The Hollywood Reporter.

Based on the graphic novel by Fred Van Lente and Andrew Foley, the story focuses 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, Arizona

The story draws a parallel between the American imperialist practice to conquer the "savage" Indians with its advanced technology and the aliens' assault on Earthlings, who must join together to survive the invaders' attack.

Hawk Ostby and Mark Fergus adapted the script.

A Summer 2010 release is planned...

How will this project (among others in which Downey is attached) affect Iron Man 2?...
