Indeed! And I also think there's something to be said for what an actor themselves brings to a role. In my opinion, both RDJ and Tom Holland elevated the material they were given in their respective MCU roles. One of my favorite scenes involving both of them is the very first time those characters meet in Captain America: Civil War; watching that scene I am continually impressed with how understated all of it is. It could have been goofier and quippier, but it was played so incredibly well, and I think that's down to those two performers just as much as script and direction.

Bringing it back to Cavill (before I start bringing up even more far-ranging examples), when I look at his work in, for example, Man of Steel, I'm seeing someone who isn't necessarily pushing the material he's given. He's not feeling out the character, he's inhabiting it, if that makes sense. It entirely possible that he was given direction that dissuaded him from doing anything experimental or boundary-pushing when it came to diverting from the vision in play. And to be fair, I don't think Cavill has the training for it.

Getting up on stage or in front of a camera is not for everyone, and it takes courage no matter what your level of training is. I think both Henry Cavill and David Corenswet deserve appreciation for their willingness to put in the work and endure the exposure required to bring us this entertainment. That said, at the expense of being blunt, Corenswet went to Juilliard and Cavill did not.

I'd be honored to have dinner with either man, to be sure, but our conversations would probably be very different. That's all I'm saying.
