Will the R-rated comedy The Hangover be a hit when it opens on June 5? It’s starting to look that way. Besides the fact that the film’s sequel has already been greenlit, early peeks at the latest movie from director Todd Philips (Old School) are hilarious — like its red-band trailer (embedded below), which premiered today. Now, I’ve seen the movie already, but one thing in the today’s clip surprised me: It gives up one of the best reveals of the movie, Mike Tyson. Yes, this trailer is riotously funny and the faux drama conveyed through Phil Collins’ In the Air Tonight is genius. But rather than hear Tyson sing now, don’t you think the laughs would have been bigger if Tyson’s warbling came as a surprise as the movie unspooled? I guess they just couldn’t keep what was supposed to be a secret quiet any longer. Take a look and let us know what you think. And, either way, are you psyched for the film?
