Brandon Routh As Iron Man!

Thinking of anyone other than Robert Downey Jr. as Tony Stark, aka Iron Man is like committing a crime "“ you are going to be hated once you reveal it! And, we are not saying that we have a better alternative to RDJ. But if, and only if, we were to build the Marvel Cinematic Universe with DC actors, we would have picked Brandon Routh for the role.

The main reason for picking Routh for the role is that he plays Ray Palmer, aka the ATOM, in the CW's DC Universe. Live-action adaptations of both the Marvel and DC characters are similar to quite a good extent. Plus, we shouldn't underestimate Routh as a TV actor as he played the titular superhero in Bryan Singer's Superman Returns "“ which also earned him a number of awards including Saturn Award for Best Actor.

Emily Bett Rickards As Pepper Potts!

Gwyneth Paltrow is the one who plays Tony Stark's love interest/secretary Virginia Pepper Potts. Among the actress we have from DC's big-screen and small-screen universes, we would pick Arrow's Felicity Smoak cast Emily Bett Rickards for the role. These two live-action characters are most alike, the only apparent difference is that Felicity is more talkative than Potts. However, if Emily can work on that, she would make an impressive version of the Marvel character.

David Ramsey As War Machine!

The role of James Rhodes,aka the War Machine, has been played by two different actors in the Marvel Cinematic Universe "“ Terrence Howard and Don Cheadle. David Ramsey, the actor who plays John Diggle in Arrow, is our pick for the role of Tony Stark's best buddy. Remember how Diggle used to get irritated with Oliver in the first season of the CW series when he was first appointed as his bodyguard? That's the reaction you need from Ramsey as Rhodey when Stark irritates him!
