The Marvel Cinematic Universe is in for a huge change.

According to Den of Geek, co-director Joe Russo opened up about the upcoming "Captain America: Civil War" in a recent cover issue of Empire.

Calling "Civil War" a "psychological thriller," Russo said that "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 psychology, and it’s an extreme shift."

Part of this shift is the ending to "Civil War," which Russo promised will have an extreme impact on fans of the Marvel franchise. Russo promised a "very dramatic ending that will be controversial for a lot of people."

This is in-line with previous statements from Russo talking about the upcoming shift in the overarching Marvel Cinematic Universe. Speaking to The Guardian in January, Russo said, “It’s cyclical. Some new Avengers in [future movies] are going to become prominent and then maybe some Avengers might not be around any more.”

Spider-Man, Crossbones, and Black Panther will make their debut in "Civil War" and other new heroes, Doctor Strange and Captain Marvel, will get their own solo films in the future as well.

So what could this "dramatic ending" Russo is referring to be about?

Warning: We're heading into potential spoiler territory here.

If you've read the "Civil War" series, of which the film is loosely based, Captain America didn't survive and was later replaced by current Winter Soldier, Bucky Barnes.

While the films are independent of the comics, Steve's death may be the exact "controversy" Russo is teasing. And, losing the original Avenger will certainly send shockwaves throughout the Marvel universe.

We'll see what the future holds for The Cap when "Civil War" releases on May 6.
