Live Poll: Who Should Be the Next Superman?

I would go more realistic, your list is composed of every popular male actor right now. But I would be surprised if the actors that play Superman is affiliated or has been affiliated to a superhero movie in recent years.

So I would also remove:

Micheal B. Jordan (He played Killmonger in Black Panther)

Jake Gyllenhaal (He played Mysterio recently)

Miles Teller (He played Reed Richards in Fantastic Four)

Idris Elba (He played Heimdall in the MCU)

Ed Skrein (He played Ajax in Deadpool)

Tom Hardy (He played Bane in The Dark Knight Rises)

Scott Eastwood (He played a character in Suicide Squad)

Actors can play multiple roles.

=====

Josh Brolin - Thanos and Cable (He was in a DC movie too)
Ryan Reynolds - Deadpool and Green Lantern
Ben Affleck - Batman and Daredevil
Chris Evans - Captain America and Human Torch (He was also in a DC movie)
Natalie Portman - Evey and Jane Foster
Hugo Weaving - V and Red Skull
Michael Fassbender - He also played a character from both DC and Marvel
Halle Berry - Catwoman and Storm
Tom Hardy - Bane and Venom
Micheal B. Jordan was in Fantastic Four too.
Michael Keaton - He appeared in many DC & Marvel movies
James Marsden was in X-Men and Superman Returns
Idris Alba was in a DC movie before playing a character from Marvel.
Jared Leto - Joker and Morbius (upcoming)
Christian Bale - Batman and a character in the upcoming Thor film (rumored)

...there are more.

Most of the actors that you named weren't associated with a character or played in two superhero movies separated by a big gap.

Josh Brolin (As Thanos is completely CGI, no one recognized him)

Ryan Reynolds (He was cast for Deadpool because Green Lantern its sequel got canceled)

Ben Affleck (There is a 13 years gap)

Chris Evans (Stupid decision)

Natalie Portman (V for Vendetta is owned by DC, but often not recognized as a superhero film)

Hugo Weaving (Same thing)

Michael Fassbender (No one cars about him in Jonah Hex)

Halle Berry (Stupid decision that can't be explained)

Tom Hardy (There will be a sequel to Venom, he is not gonna play in both DC and Marvel at the same time!!!!)

Michael B. Jordan (Stupid decision)

Michael Keaton (Lol, there is a huge gap between 1992 and 2017)

James Marsden (Stupid decision)

Idris Elba (The losers is not recognized as a superhero film)

Jared Leto (His role is minor in suicide squad

Christian (Your rumors aren't pertinent)

Ok fine, if you want to keep the rest...

But at least delete Dwayne Johnson and Tom Hardy, they aren't gonna play two superheroes at the same time.

  
Superman (1978)
https://www.imdb.com/title/tt0078346/reference
Christopher Reeve ... Superman / Clark Kent 
  
Numerous actors were considered for the part of Superman a.k.a. Clark Kent, including:
... Arnold Schwarzenegger
.

From your picks, my favorite Superman would be Idris Elba, but my favorite Clark Kent would be Cillian Murphy. I would potentially cast Zachary Quinto as a villain.

 Thank you!
