Why can Batman and Spider-Man survive recasting, while Iron Man or Wolverine feel tied to one actor?

I’ve been wondering why recasting works so differently depending on the character.

Batman and Spider-Man have both had several actors, and people seem able to accept a new version pretty quickly.

But with some characters, the actor and the role almost become the same thing. RDJ as Iron Man is the obvious example for me, and Hugh Jackman as Wolverine feels pretty similar.

I’m not sure it’s just about how good the actor was, though.

Maybe it matters how long they played the role, how successful that version became, whether the character was already famous before them, or how much the actor actually shaped the character people know.

So why do you think some characters survive recasting easily while others feel almost attached to one actor?

And which characters do you think would be hardest to recast?

Batman and Spiderman have been popular for decades.
RDJ and Hugh Jackman are the reason why Iron Man and Wolverine are popular.

This is it exactly.
