Everyone does the job of acting in his own way , so they all seem different .
some would have felt that heath ledger won't play the joker they expected , but after the movie came , MIND=Blown off. Every actor does a role prior to how the character is to be shown by the scripts and all , and given that they do their best .
So lets just say we maybe able to watch the character in a different angle , like in all different anime, cartoon , movies . So looking forward to it .
