We just need to accept a simple fact - that Ledger died of a drug overdose, naked and alone in a motel room. It does not automatically mean, he died preparing for the role and that he deserves our sympathies for the same. It is not exactly bollywood that actors do parts in 5 movies at a time. So if Ledger over prepared as is being sympathetically proposed, too bad he failed to take the pressure. To me this is not any less gimmicky than Aamir Khan living the character of his upcoming movie. As someone once said, 'method actors must try acting for a change'. Anyway, I wish Ledger's performance shapes up well.
