I wouldn't want to know the people you do then. People who go and see this film, just because they think it's Heath Ledgers last are morbid. And how they'll sit through a 2 and a half hour film in which he's not in every scene is beyond me if they have no interest in Batman whatsoever.
If theres a small percentage of people who actually go and see this just because of Heaths death, then it's just that, a small percentage.
I never knew Heath Ledger had so many fans? He sure as hell didn't when some of his other films were released.
PS This isn't his last film, 'The Imaginarium of Doctor Parnassus' is his last film, so maybe inform your frienRAB that they've misunderstood the press and it must be the press since the movie company has made no reference to this being his last film.
