VIDEO: Watch the First Trailer For 'The Hangover: Part II'

Some sequels just take the story from the first movie, move it to a new location, and expect us to be impressed. "The Hangover: Part II" is one of those sequels, but we might just end up actually being impressed.

The first trailer for the sequel was revealed by Warner Bros. at CinemaCon on Thursday, and it looks like more hilarity and mayhem. Once again, the guys have a wild night for a bachelor party (this time Ed Helms' character Stu is the one getting married) but this time they're in Thailand.

What's different? A monkey is along for the ride, Zach Galifianakis has a shaved head, Ed Helms has a face tattoo, and Justin Bartha isn't the one that's lost...it's the little brother of Stu's bride-to-be. It looks like Ken Jeong might be playing a larger role in this "Hangover," which makes sense as he has gained a bit of a profile from his appearances on NBC's "Community."

It looks like there might be more action in this installment, as Thailand looks to be pretty dangerous for the boys. I'm just hoping Ed Helms treats us to another impromptu song.

Here's the trailer in its full glory. What do you think: great sequel, or same ol' thing?
