As the UK’s big three-weekend rolling convention rolls on, Kapow! is the big multimedia/Big Two and Image/mancave convention, with movie premiere stuff, Joe Quesada, Dan DiDio, Eric Stephenson, Jonathan Ross, and even Warren Ellis and Peter Serafinowitz. The show is being held at the fairly intimate London Business Design Centre—total capacity is about 6500 people—and all tickets are already sold out, meaning there will be no walk-up tickets at all—so mastermind Mark Millar’s wish to give the UK a mini San Diego has come true.
