When that Heath Ledger Joker-trauma quote began making the rounds last Tuesday — the late actor confiding that playing “a psychopathic, mass-murdering, schizophrenic clown with zero empathy” in Chris Nolan‘s The Dark Knight caused him to sleep only “an average of two hours a night” — it seemed lurid to even suggest that his acting in the forthcoming Warner Bros. film had obliquely contributed to his apparent sleeping-pill death. But Jack Nicholson‘s comment about Ledger’s death in London three days ago — “Well, I warned him” — means that this allusion/association isn’t going to go away.
