The unstoppable Dark Knight Dark Publicity&trade campaign—what Terry Gilliam describes as a "great white shark which devours whatever it can"—continues to feed hungrily on bad-news chum. We're still waiting for more specific details on what Christian Bale did, exactly, to his mother Jenny, 61, and sister Sharon, 40, that led the two to file assault charges against the actor, ultimately leading to his arrest today at London's Dorchester Hotel. As The Sun first reported, the actor, in town for the European premiere The Dark Knight, "lashed out" at the family members at the hotel Sunday night. Both lodged a complaint yesterday, but officials apparently held off for Bale to attend a series of press conferences and last night's premiere in Leicester square. A police spokesperson would only offer: "A 34-year-old man attended a London police station on Tuesday by appointment and was arrested in connection with an allegation of assault. He currently remains in custody."
