What fictional character made you hate the celebrity playing them?

I find myself thinking from time to time about Jack Gleeson, the actor who played Joffrey on Game of Thrones. Dude was SO good at playing a petulant brat, that people in real life reacted so strongly to him, associating him with Joffrey despite the fact he's quite different. It's unclear if that was at all connected to why he quit acting, but I would think getting hate mail because of a character you played would not be fun.

But it also makes me think: what other actors do you hate BECAUSE of the part(s) they’ve played in film and on TV. For example, if I ever saw Shooter McGavin in person, I would assume he was the WORST. Sometimes actors are just too good at their jobs…
