"Captain America: Civil War" is one of the most anticipated films of 2016 and is expected to be big, considering the list of actors who are on board.

"Civil War" will introduce new heroes and also bring back other characters from previous installments or other Marvel movies to make for an explosive superhero flick.

WhatCulture noted that the entry of new actors and the return of the old ones should somehow bring disappointment to many fans due to their portrayal or the deviation from the original story in the comics.

For instance, Daniel Brühl made fans happy when it was revealed he will be playing a fan-favorite, Baron Zemo. Baron Zemo has attracted a strong fan base but "Civil War" might disappoint his fans, especially when Bruhl himself recently revealed that the iconic character won't be putting on his mask.

"He does not wear the mask," the actor told Business Insider last month. "You would be surprised, it's different than what you'd think."

There's also the deviation from the "Civil War" comics version, in which Iron Man became the bad guy. According to WhatCulture's review, the production won't dare make Tony Stark a bad guy as he needs to maintain a good image for the tickets. Nevertheless, scrapping out that storyline for the upcoming Marvel movie would be frustrating for comic book fans.

However "Civil War" will turn out, many still expect it to be fantastic. Paul Bettany, for instance, revealed in an interview with Collider that he thought the script was interesting. When asked about "Civil War's" script, Bettany, who stars as Vision, responded that the movie "is going to be a lot of fun."

Meanwhile, an official trailer for the film has yet to be released. Design & Trend reported that the Russo brothers announced that "the trailer is almost complete." No exact date has been given away, but fans should definitely watch out for it to find out if "Civil War" will disappoint or not.

"Captain America: Civil Wars" will premiere on May 6, 2016.
