Check out the hilarious new trailer for Todd Phillips’ “The Hangover” Brighten up your Monday morning with the hilarious new teaser for Todd Phillips’ new comedy “The Hangover”. Two days before his wedding, Doug and his three friends drive to Las Vegas for a blow-out bachelor party they’ll never forget. But, in fact, when the three groomsmen wake up the next morning, they can’t remember a thing. For some reason, they find a tiger in the bathroom and a six-month-old baby in the closet of their suite at Caesars Palace. The one thing they can’t find is Doug. With no clue as to what transpired and little time to spare, the trio must retrace their hazy steps and all their bad decisions in order to figure out where things went wrong and hopefully get Doug back to L.A. in time to walk down the aisle. Part “Three Men and A Baby”, part “Fear and Loathing in Las Vegas”, “The Hangover” stars Bradley Cooper, Ed Helms and Heather Graham and opens in Irish cinemas July 31st. The first trailer may be short but it’s packet full of laughs and if the sight of Mike Tyson singing Phil Collins doesn’t get your bum in the cinemas seat, we don’t know what will!
