Nathan Fillion As Ant-Man – While Nathan Fillion has downplayed the idea that he will play Ant-Man, fans of the actor are still clamoring to see him in the role. Joss Whedon also gets some of the credit for keeping this rumor going, as he jokingly announced at Comic-Con a couple years back that Nathan Fillion would play Ant-Man in the first Avengers movie. Of course, with an Ant-Man movie now announced, it will likely be director Edgar Wright who casts Ant-Man (even though Joss Whedon might have some say as well given his new exclusive contract with Disney).
Vin Diesel As The Vision – The possibility of Vin Diesel playing the Vision came out of the blue, as in the popular blue-border Facebook fan page of Vin Diesel where his profile picture was updated to an image of the Vision. Is Vin Diesel being considered for the role? Or is he just campaigning for the role? No one knows for sure, but he would definitely add some more star power to a movie already filled with stars.
Clark Gregg As The Vision – While Vin Diesel might be campaigning for the Vision role, many fans are campaigning for Clark Gregg to be given the role. In addition to bearing a striking resemblance to the Vision, Clark Gregg also became a fan favorite among comic book fans for his portrayal of Agent Phil Coulson in various Marvel Studios films. The bottom line is that fans don’t want The Avengers to be the last they see of Clark Gregg in a Marvel Studios film. Fans want him back, and the Vision seems like a good way to bring him back.
Chiwetel Ejiofor As The Black Panther – For awhile, there were rumors that Black Panther would be the next Marvel Studios film announced. However, those reports proved to be untrue, but many fans are still itching to see the Black Panther on the big screen. It would be great to see him join Avengers 2, and there are a lot of actors campaigning for the Black Panther role. However, Chiwetel Ejiofor and Anthony Mackie seem to be the names that come up the most among comic book fans. And with Anthony Mackie already reportedly in talks to play The Falcon that leaves Chiwetel Ejiofor as a perfect fit for the Black Panther role.
Olivia Munn As The Wasp – Black Widow was kind of lonely in The Avengers, and The Avengers sequel definitely needs to add another female character. The Wasp seems like one of the most likely choices, and Olivia Munn is definitely a familiar name among comic book fans. She was rumored to be under consideration for the role of The Wasp a couple years back, and her career has only gone up since that time. With a recent appearance in the movie Magic Mike and her regular role on the HBO series The Newsroom, she just might be ready to make the leap to a big blockbuster film like the Avengers 2.
