It’s already one of the most anticipated movies of next year, and now the first teaser trailer has arrived for Cowboys & Aliens, which is directed by Jon Favreau (Iron Man), and stars Daniel Craig, Harrison Ford and Olivia Wilde. It’s a pretty cool tease, starting off looking like just a run of the mill western, with Craig as a man with no name or memory who wanders into a small frontier town. So we got the Cowboys, but where’s the Aliens? Well, they arrive towards the end of the teaser, launching an attack on the town. It’s all pretty cool, and successfully sets up the story, with Craig’s character as the only person who may be able to stop the extra-terrestrials abducting everyone in the old west, partially thanks to a strange device attached to his arm. The movie is due out in the UK August 12th, 2011, but click below for the first teaser.
