Full trailer for The Hangover…and a sequel already greenlit?

Todd Phillips’ The Hangover isn’t due to hit theater until June 5th, but apparently Warner Bros. has already asked Phillips and his writing partner, Scot Armstrong, to work on the screenplay for a sequel, which has Phillips back to direct and produce, and stars Bradley Cooper, Zach Galifianakis and Ed Helms all on board. This according to reports on various websites.

In The Hangover, the trio play best friends who go to Vegas for their best friend’s stag party and wedding, only to lose the groom (Justin Bartha) hours before the ceremony.

Check out the full trailer below.
