"Captain America: Civil War" is going to shake things up in the Marvel Cinematic Universe. Not only will heroes fight heroes when Captain America (Chris Evans) faces off against Iron Man (Robert Downey Jr.) in the upcoming Marvel movie, but one of the directors of the film says that the way the movie ends will be a big game changer. 

According to Empire Magazine (via ComicBookMovie.com), "Captain America: Civil War" co-director Joe Russo said the upcoming film will have a "controversial" and "dramatic " ending. The movie is expected to set the stage for the next series of Marvel films, including the highly-anticipated "The Avengers: Infinity War."

"The consequences of Civil War will have an even more significant impact [than 'Captain America: The Winter Soldier']. In 'Civil War,' we're going to change the Marvel Cinematic Universe's Ppsychology, and it's an extreme shift," Russo dished. 

During the Wizard World Comic Con New Orleans, ComicBook.com reported that co-director Anthony Russo teased that some of the heroes would come out of "Captain America: Civil War" in "body bags." This suggested that fans might see some of their favorite heroes killed off in the next chapter of the Marvel Cinematic Universe.

This follows rumors that have been circulating that Captain America will be killed in the film. In the comics[POTENTIAL SPOILER ALERT] Steve Rogers is assassinated on the steps of a courthouse after surrendering. Bucky Barnes a.k.a. the Winter Soldier (Sebastian Stan) then takes on the role of Captain America.  The two behind the assassination are Crossbones and Sharon Carter. Both character will be in "Civil War," as Crossbones will be played by Frank Grillo and Sharon Carter by Emily VanCamp.

However, there are still reasons for Captain America fans not to worry if Rogers does indeed die in the film. When Captain America was shot in the comic books, the bullet that went into Rogers did not kill him, it instead only made it appear that way. Moviepilot also notes that Evans signed on for six Marvel movies and has only appeared in five films, including  the upcoming "Civil War." This means there's room for him to return in one of the "Infinity War" films if he does get killed in "Civil War." It's also noteworthy that Stan's contract is for nine movies and he's only been in two so far.

Do you think the death of Captain America will be the dramatic ending the "Civil War" directors were hinting at? Sound-off in the comments section below:
