First with Ben Affleck as the DC Cinematic Universe's official Batman
Surely things got a little rough for the actor when some fans were infuriated by him being cast as the Dark Knight but still he is Batman and I don't mind because all that matters is that we got someone we know very well doing the part. As we speak, Affleck has been working out a lot while preparing for his role in the highly potential blockbuster film and his version of the character is sure to be just as real as anything in our world and after playing Daredevil in the 2003 film, Affleck should still have the skills to pulling off a very potential Batman here in the DC Cinematic Universe. All that is left unsaid is whether he will be able to sustain his role as Batman in the DC Cinematic Universe or not because sometimes actors have to participate in other movies that are not comic based and sometime the actors themselves will need a long break before they can continue their parts in future comic based films.
Next up is Callen Mulvey
After working in recent action films such as 300 Rise of an Empire and Captain America the Winter Soldier,
Mulvey has been officially cast in Zack Snyder's Man of Steel sequel and knowing how pleased the director himself is with having to work with Mulvey again, he is sure line him up for a really good part in the film. Recently the actor has been rumored to pay Lex Luthor or Metallo over the past couple months and since Jessie Eisenberg has been cast as Luthor, Callen Mulvey is very much likely to portray the super villain known as Metallo. While it is not yet confirmed, the reason that Mulvey is sure to portray Metallo is because of some of the previous movie roles he has done, he is very much more of a physical type of actor so his role in the Batman vs Superman film is most likely to be a villain and Metallo is definately rhe kind of villain that Snyder would have him pull off in the film.
and now for Tao Okamoto
As a rookie who just began her film acting career in The Wolverine, Tao is brand new to this kind of thing and now after participating in a Marvel Comic based film, she is now participating in DC Comic based film. While her role is yet to be announced and unsure if the character she is pllaying in the film is from the comics or just made up, Tao's role is sure to be a supporting character. If her character isn't major from the comics she could be playing an employee at either Wayne Industries or Lex Corp, or since she is Japanese born asian, there is a very slight chance that she could be playing a character who has never yet been seen in the cartoons or the films. A character who helps Batman fight against evil who is also a major part of the Bat Family. A character named Cassandra Cain, daughter of of assassins David Cain and Lady Shiva who originally served as Batgirl and now goes by the code name Black Bat. While it may not seem possible for Okamoto to portray Cassandra in the upcoming Batman vs Superman film, all we can do is wait and see who Snyder has the lovely lady doing and if there is any luck that she will play Cassandra Cain, then it will be a great pleasure to finally get to see the character in the media for the first time and if not, well you know what they say, you can't always get what you want, can you?
Well that's that on what there is to know on the three Marvel film actors that are cast in the film. All we can do now is wait and hope things turn out good.
