What actor was perfectly cast in a role nobody else could’ve pulled off?
Not necessarily the best performance ever, but one where the casting felt so perfect that it’s hard to even imagine another actor doing it.
Could be because of the actor’s personality, voice, look, chemistry with the cast, or just how naturally they fit the character.
For me, Heath Ledger as the Joker is one of those roles where I genuinely can’t picture anyone else matching that energy.
