If the first poster for The Hangover Part III is any indication, come May 24, Las Vegas has a lot more to fear from the Wolfpack. Zach Galifianakis and Ken Jeong are fiercely facing off as Alan and Mr. Chow, and they look a lot like another hero/nemesis duo we know. The likeness to the poster of Harry Potter and the Deathly Hallows: Part 2 is definitely on purpose, right down to the "It All Ends" tagline, and I kind of love it. Get a load of the one-sheet and compare it side by side to its magical counterpart.
