Yippee Ki-Yay, Extraterrestrial! It’s ‘Cowboys & Aliens’ (Video)

Here’s what the trailer tells us: Daniel Craig is packing serious alien heat, Harrison Ford is seriously grouchy

Jon Favreau's first post-"Iron Man" project is in the can, and — look up in the sky, pardner! Here comes the coolest trailer you'll see this week.

Much of the footage is from a scene that Favreau showed the crowd at Comic-Con this year: When a deeply grumpy Harrison Ford shows up to claim fugitive Old West cowboy Daniel Craig from local authorities, a transaction that's interrupted by space aliens.

Oh yeah, and Olivia Wilde!

"Cowboys and Aliens" comes out in July.
