I think its a bit far fetched to say that Ledger was Legend Material.He hadnt even reached his peak yet.He was only 28 and his best years were ahead of him.Not to draw any comparisons,but actors like Jack Nicholson,Al Pacino,De Niro,Marlon Brando..they were all into their 30's when they made it BIG and turned into the icons that they are today.Ledger as an actor,was talented,and he was definatley on the rise as far as critical success is concerned.But exactly what he might have acheived is anyone's call.He might have gone on to become an icon,or he might have self exploded.As things stand today,he'll go down in the books as a very talented actor,who died at a pretty sad age.
