We know that a civil war is on the way in the Marvel Cinematic Universe. We know who will be on Iron Man's team and who will be on Captain America's team. But what will happen to split the Avengers apart in the first place?

Speaking at Salt Lake Comic Con this past weekend as part of his first-ever solo panel, Chris Evans told his fans just what will put Tony Stark and Steve Rogers on opposing sides when "Captain America: Civil War" hits theaters next year: when the government wants all superheroes to sign accords and be held accountable for their actions, Tony will be on board and Cap won't be. Wait, say what?

"Tony actually thinks we should be signing these accords and reporting to somebody and Cap, who's always been a company man and has always been a soldier, actually doesn't trust anymore," Evans said, as quoted by the Salt Lake Tribune. "Given what happened in 'Cap 2,' I think he kind of feels the safest hands are his own. And these are understandable concerns, but this is tough, because even reading the script, you think, 'I think I agree with Tony in a way, and I do agree that to make this work, you do need to surrender to the group.' It can't just be one person saying this is right and this is what we're going to do."

"But Cap has his reasons, he certainly has his reasons, and he is a good man and his moral compass is probably the cleanest. This is a tough thing. This is what made it so interesting while we were filming, and it's hopefully what will make the movie great -- nobody's right, nobody's wrong. There's no clear bad guy here. We both have a point of view, which is akin to most disagreements in life and politics."

At first glance this seems like it's against everything we know about Tony, the guy who refused to let the U.S. military have his Iron Man suit, and Cap, the guy who literally worked for the U.S. government. But it lines up pretty closely with the "Civil War" storyline in the comics, where Tony becomes a champion for the Superhero Registration Act (which requires all superpowered humans to disclose their true identities to the government and undergo training) and Steve Rogers opposes the act on the grounds that it's an invasion of privacy.

Either way, it's nice to see that the new movie will be complicated, with both teams having good points and bad. Which do you think you'd follow?
