I worked the Oscar circuit in 2006 and watched Mr. Ledger in support of “Brokeback Mountain,” then a favorite for best picture, and can say he never was much of a campaigner. A polite, nice man, he had little aptitude or appetite for trite talk at parties or events, even when he was up for a best actor Oscar, as he was then. For “The Dark Knight” the studio has eschewed any R.I.P. allusions in its trade advertising, instead relying on a steady (and not frantic) visual presence of somebody now best known for his absence, showing him in various guises: the crazed man in the nurse’s uniform, the immovable object standing in the middle of the street.
