Derivative? Check. Well reviewed? Not really. Kicking crazy ass at the domestic box office? Oh, hell yes. I am, of course, talking about Warner Brothers’ The Hangover Part II, the film that has already broken the one day record for a live-action comedy with its stunning $31.7 million Thursday debut. That was on top of its $10.4 million midnight take – easily the highest of 2011. Day two for the Wolf Pack brought in an additional $30 million from 3,615 locations, giving the film a current estimate of $61.6 million in total. If projections hold, The Hangover II could end up with a five day total of over $135 million and a spot in the top five of all-time (four-day) Memorial Day Weekend debuts.
