Actors/Actresses who were the perfect casting for their role
A thread inspired by the "Actors/actresses who played in movies that are not suited for them" thread, but the opposite.
Basically, which roles/parts you feel where the person that was cast ended up being pretty much perfect for the role.
To get things going, I am going to say Chris Evans as Captain America. He really owned that role and made it his own. And, as such, it's extremely hard for me to picture anyone else as Cap, despite knowing that there have been other live-action incarnations before him.
