I hadn't heard of this movie until Thursday. I love this trailer and now can't wait for the movie -- crude though it appears to be (and I'm not remotely a fan of crude). But it's so unabashed and nonchalant with what's going on, that I admire that matter-of-fact attitude. Besides that, there are a couple of sequences that had me literally laughing out loud. That's tough to do in any trailer, let alone one being watched alone on your computer. My favorite sequence might be the one where he's being taught how to shoot.
(There's also a very subtle quip sitting around an Indian campfire that has an allusion to an actors. It's cute-ish, but what I particularly liked was that it was someone who had been in Ted, which for me is the better joke and might slip past some.)
The premise concerns a young sheep farmer who backs out of a gunfight, so his girl leaves him. Then a beautiful woman with a problematic past enters the town, and...complications ensue.
The film has a strong cast, including Charlize Theron, Liam Neeson, Amanda Seyfried, Neil Patrick Harris and Sarah Silverman.
