A brand new poster for Jon Favreau‘s upcoming graphic novel adaptation, Cowboys & Aliens, has been released online via Yahoo! Movies.

The poster is simple but exciting enough for those of us itching to see the movie. The poster also serves a double-purpose: to keep us excited for the movie, which will be released next summer on July 29, 2011, and to set up the countdown to the movie’s first trailer, which is just a couple of days away now!

The movie stars Daniel Craig, Harrison Ford, Olivia Wilde, Sam Rockwell, Adam Beach, and Paul Dano, and tells the story of an alien invasion in late 1800s Arizona, forcing rival cowboys and Indians to join forces and take on the intergalactic threat before it’s too late.

Back on April 5th, director Jon Favreau dropped a tiny little teaser note on Twitter that some juicy casting news would be coming in regards to his upcoming adaptation of the comic book Cowboys & Aliens.

Before that, Latino Review had heard whispers that Harrison Ford was actually joining the cast of a big comic book movie and put the two pieces together. Nothing was official at that point, but Mr. Favreau has finally confirmed once again via his Twitter account that Indiana Jones has definitely joined his movie.

Favreau’s big reveal was simple and straight to the point, as 140-characters can sometimes force you to be. “Please stop asking if Harrison Ford is in Cowboys & Aliens. Okay? He is. Please don’t tell anybody,” he said.

Back in September we discovered that Jon Favreau may be working with his Iron Man star Robert Downey Jr. again soon when he became a candidate to direct a movie based on the Scott Mitchell Rosenberg graphic novel, Cowboys & Aliens. Since then, Favreau has officially become the director, but unfortunately, Downey Jr. actually had to drop out of the project this past Monday.

Now comes word via a scoop by Collider that Casino Royale and Quantum of Solace‘s James Bond, Daniel Craig, is now in negotiations to take on the role of Zeke Jackson that Downey Jr. vacated.

Cowboys & Aliens isn’t the most recognizable title in the world of graphic novels, but its premise sounds to be highly entertaining. It takes place in Silver City, Arizona sometime in the 1800s where the Cowboys and Indians are fighting it out as we all know they did, but this particular location is about to have a bit of a twist.

A little over a year ago, it was reported that Robert Downey Jr. was attached to star in an adaptation of the Scott Mitchell Rosenberg graphic novel, Cowboys & Aliens. It appears now that his Iron Man and Iron Man 2 director Jon Favreau may be hoping to join the party as well.

Nothing is official yet, but it would be a great job for anyone to land, considering the veritable powerhouse studio tag-team of DreamWorks, Universal (and possibly Paramount for distribution) and larger-than-life producing group of Brian Grazer and Ron Howard of Imagine Entertainment, as well as Steven Spielberg. Also producing is Rosenberg and Alex Kurtzman and Roberto Orci.
