He’s no longer cast as expendable crewman No. 6.

Sam Rockwell has been cast as saloon owner Doc, in Jon Favreau’s next movie, Cowboys vs. Aliens.

When Favreau learned of Rockwell’s interest in the film, he and writing partners Alex Kurtzman, Roberto Orci and Damon Lindelof, reworked the script and expanded the role just to bring him on board. They even went so far as to modify the appearance of the character to suit him.

Daniel Craig, Olivia Wilde and Harrison Ford also star.

Cowboys vs. Aliens is produced by Steven Spielberg, Ron Howard and Brian Grazer with Scott Mitchell Rosenberg for Dreamworks. It will bow into theaters on July 29, 2011.

Sam Rockwell’s latest movie is also directed by Jon Favreau. It’s a little film called Iron Man 2. Maybe you’ve heard of it?
