Superman/ Henry Cavill
One of the most obvious choices would be Henry Cavill for the role of Superman. That one we won’t have to debate very much on.
Batman/ Matt Bomer
In the comics and most animated versions of Batman have a resemblance to Superman’s physical characteristics? Matt Bomer, and Henry Cavill share some similarities in their appearance. I know some are aware of Matt Bomer coming out of the closet recently, but why should that obscure his portrayal of the Dark Knight. An actor’s job involves trying to create an illusion for us to believe, and he’s done that for years (the playboy type). He was also once considered to play Superman in the past. Currently he is one of leads on the hit show White Collar, and is staring in 50 Shades of Gray. Matt Bomer has also voiced his talents for the upcoming Superman Unbound animated movie.
Wonder Women/ Kelly Thiebaud
I’ve consider Kelly Thiebaud as one of the “off the radar” actresses based on her athletic appearance (5’9”), and physical abilities. She has a very exotic look, and can also play a tough heroine type. Currently Kelly Thiebaud plays a doctor on the soap opera General Hospital.
Captain Marvel/ Joe Manganiello
Another actor once thought of as a frontrunner for the role of Superman could lend his capabilities for another role as Captain Marvel/ Shazam. His appearance would be better suited for a sequel.
The Flash/ Ryan Kwanten
Most of us know Ryan Kwanten as Jason Stackhouse on True Blood. He has proven to play the juvenile type by adding a humorous personality, and becoming a strong figure on TV. As The Flash he would be a perfect fit, centered, on his personal pursuits; triathlon, a boxing champ and other activities from his native Australia.
John Steward/ Michael Jai White
Based on his past interpretations of action characters, Michael Jai White may have the power to erase the original adaptation of The Green Lantern from the last movie. Well versed in martial arts, his fighting capabilities would translate well on screen. His performance on Black Dynamite shows he has range to play other roles.
J'onn J'onzz/ Lance Reddick
From the recently completed series on TV; Fringe, as well as from other hit shows like OZ, and The Wire. Lance Reddick has a presents of authority which is appropriate for the part. His characters voices resemble the nature of J’onn J’onzz from the animated Justice League series.
Darkseid/ Kevin Grevioux
Most recognized from playing a Lycan from the Underworld Series, and now doing voice over work on Young Justice as The Black Beatle. Kevin Grevioux is actually a huge fan boy of comic book related media. He also helped to create some of the material for Underworld. Besides understanding the fantastical elements used to translate ideas onto TV, and movies he already has the voice, and build for Darkseid without any special enhancements.
All of the actors mentioned above are all physically fit, and most are above average actors who are more than capable to perform exceptionally well, and surprise us entirely in their perspective roles. All of them have already portrayed their counter parts in one way or another through their past and present jobs. Thanks for taking some time to read my list. I would like to compile another listing in the future with an inventory of villains.
