Now that Iron Man 2 has come and gone, director Jon Favreau can focus on his next summer blockbuster Cowboys & Aliens. The film is a sci-fi/western hybrid that centers on exactly what the title suggests…cowboys and aliens. It will star Daniel Craig as the main gunslinger along with Indiana Jon– we mean Harrison Ford. Favreau recently tweeted the first photo from the film’s production and it has us yearning for more…

Favreau didn’t give any major spoilers regarding the picture besides the fact that it’s being used for camera tests.

We’re assuming this cowboy in particular will be Craig’s character Zeke Jackson. Cowboys & Aliens will center on outer-space creatures who land in Arizona circa the mid-19th century intent on enslaving the local population — until a group of cowboys and Apache Indians fight back. Jackson is a very talented gunman and will be the revolt leader.

Production on the film hasn’t begun yet but when it does we’re expecting to see a lot more exclusives popping up from Favreau’s camp. Cowboys & Aliens is scheduled to hit theaters on July 29, 2011 and also stars Noah Ringer, Sam Rockwell, and Paul Dano.

What do you think of the first photo from Cowboys & Aliens? What do you think of the costumes being used for the film?
