Just curious what your thoughts are on this. Is it tougher to recast a superhero or supervillain character that has previously been portrayed by another actor if the performance was universally loved, or universally panned. Take, for example, Heath Ledger's Joker. This is a character that everyone liked. Now, I know the circumstances are different here due to Ledger's untimely death, but, I think there's a chance that even if he was still alive, the inevitable Batman reboot would not want to revisit the character of the Joker again so soon after such an iconic performance. Another good example would be Robert Downey Jr.'s beloved Iron Man. Once he decides to hang it up, would another actor want to go near that role? Now look at the reverse. We've seen versions of Green Lantern, Daredevil and The Punisher on the big screen (or maybe the small screen) that rubbed some people the wrong way. Although it might seem like a no-brainer to simply recast the roles, I think that sometimes if a performance leaves a bad taste in your mouth, it's like it taints the character and makes you not want to see them again. What are you thoughts?
