Guillermo del Toro brings us Pacific Rim, the apolocolyptic story of alien sea monsters waging war against the human race. Many are comparing this film to the box office hit Independence Day with similar alien undertones and a quest to save mankind. Walking the carpet on this hot July night were stars of the film including Charlie Hunnam, Idris Alba and Rinko Kikuchi. Charlie Day entertained the crowd bringing fellow "Always Sunny" cast members Rob McElhenney, Kaitlin Olson and Mary Elizabeth Ellis along for the ride. Pacific Rim opens in theaters July 12th and is distributed by Warner Bros.
