Many of us weren't terribly excited for the upcoming The Hangover Part III, after seeing the lackluster Hangover Part II, but this newly released trailer definitely piques some interest. It opens with a funeral - for Alan (Zach Galifianakis)'s father, sadly - and then follows the Wolf Pack as they head back to the city where it all began: Las Vegas. The film will see the return of mostly the entire cast, including Jamie Chung and Heather Graham. Sadly, Mike Tyson will not be involved.

Thankfully, in addition to giving us a small taste of what to expect, the trailer also seems to prove that this film definitely won't be just like the last two. Consider us intrigued.

Also, apparently Alan has the voice of an angel. We'd be lying if we said we saw that coming.

You can check out the trailer above.
