Here are some just off the top of my head:

Chris Evans (Cap, Johnny)
Josh Brolin (Thanos, Cable)
Ben Affleck (Batman, Daredevil)
Brandon Routh (Superman, Atom)
Ryan Reynolds (GL, Deadpool)
Hugo Weaving (V, Red Skull)
Halle Berry (Storm, Catwoman)

What do you guys think?? Which actor has given us the greatest performances as their comic book counterparts? Was it someone not even in the list? Let me know! :D

From a purely acting standpoint, Brolin and weaving are probably the best. As for the roles they play, probably Evans or Reynolds( I liked the GL movie so sue me)

Ryan Reynolds or Josh Brolin.

Ron Perlman and Mark Strong.

Ryan Reynolds sucks

Brolin was also Jonah Hex

Josh Brolin or Chris Evans(only as Cap) ..........

Evans was good in Snowpiercer too.

J. K. Simmons

Ryan Reynolds, Josh Brolin, and Brandon Routh.

Chris Evans.

Weaving and Brolin act circles around everyone here.

Josh Brolin seems to stand out, this was his year though, so I may be biased.

Weaving is the best actor here from an objective perspective I think. Correct me if I’m wrong but he should have the most awards/accolades of everyone here.

That being said, I think the roles I’ve enjoyed the most here personally are Reynold’s Deadpool and Weaving’s V.

Which actor has given us the greatest performances as their comic book counterparts?

It's between Hugo Weaving and Mark Strong.

Weaving and Brolin are the best actors amongst them so far.
