Iron Man partners in crime Jon Favreau and Robert Downy Jr. may work together in Cowboys & Aliens.

Favreau is very interested in corralling this picture deal as director with DreamWorks and Universal overseeing the project. The project has Downey attached to star with a hope of starting in the summer of 2010.

Obviously, based on the title, the film is set in the Old West.  Cowboys and Native Americans battle each other in Arizona when a space ship crashes and a new enemy force makes the battle  majorly different with new technology beyond the wild frontier.

The film is based on a graphic novel of the same name that was published in 2006. The sale of the film idea came from, not the whole novel, a one-sheet of a cowboy and a space ship.

Of course, Favreau and Downey will work on Iron Man 3, but Iron Man 2 needs to open May 10, 2010 first.
