I know the Thor 2 trailer is today;'s big trailer news, but might I humbly suggest checking out the first Japanese trailer for The Wolverine (or, as they apparently call it, Wolverine: Samurai)?
It contains a good chunk of new footage, especially of the ninja-attacking, sword-fighting, ass-kicking variety — and it just makes the movie seem... better, somehow. Like it just hangs together a bit more. I'm not exactly sure why that is, but I do know that adding more ninja action has never hurt any movie at any time.
There's way more ninja action in the Japanese Wolverine trailer
