Who exactly is "true actor" for You?
Every1 of them is getting paid for doing this, They act for a living.
I disagre, people wait for Dr. Strange because he will open doors for multiverse, WandaVision and Loki did just a little peek into it, he will open it for real.
Btw, about so called "true actors" in MCU
Anthony Hopkins, Ben Kingsley, Benicio Del Toro, Forest Whitaker, Gwyneth Paltrow, Jamie Fox (sony spiderman), J.K. Simmons - those are just few people who won Oscar and are part of MCU.
Christian Bale will be in next Thor movie.
Mahershala Ali is going to be Blade and I can't wait for it since I love the guy and Blade in general
Russell Crowe is going to be Zeus in Thor.
Alot of people who took huge part in MCU are well respected actors, nominated many times for oscars etc.
Scarlett Johanson - great actess. Her role in Marriage Story or Jojo Rabbit was amazing.
My point is - "true actor" is terrible statement by You.
And its hard to say who's "good actor" nowdays since Oscars are pretty much rigged most of the time because of racism, LGBT and other stuff like that.
