4. Not Enough Ron Perlman
Del Toro regular Ron Perlman appears about 1/3 of the way through Pacific Rim, playing Hannibal Chau, a black market trader who deals in kaiju organs, a prized commodity that Dr. Geizler thinks just might hold the key to defeating the monsters. Every second of his screen-time is absolute gold; kitted out in sparkly gold shoes, a sharp suit and de-humanising glasses, Perlman plays the part of the scary, imposing honcho exceedingly well, and needless to say, he steals the few scenes he's in. Disappointingly, though, he's not in the film all that much...
SPOILER ALERT ...ending up eaten by a baby kaiju born prematurely. However, stay past the credits and you'll see that Chau does, in fact, survive, cutting himself free from the insides of the kaiju, suggesting that he'll be around for Pacific Rim 2 should it happen.
