And in other Marvel news… In addition to that Doctor Strange featurette, another bonus video from the studio’s deluxe Phase 2 box set has arrived online, this time focusing on that other highly-anticipated Phase 3 film — Captain America: Civil War. The new featurette goes inside the “rift” between Robert Downey Jr.’s Iron Man and Chris Evans’ Captain America, which causes a divide between their fellow Avengers and sparks a very personal battle between friends.

Marvel head Kevin Feige is joined by Civil War directors Joe and Anthony Russo and producer Nate Moore in the above video, which takes you inside the fight between Tony Stark and Steve Rogers, set off by the Sokovia Accords, the MCU’s version of the acclaimed comic book’s Superhuman Registration Act. Essentially, the fallout from Age of Ultron has inspired the government to take extreme measures to rid the world of what they perceive as acts of “vigilante” justice. (Imagine if Bruce Wayne stepped into the MCU at this point; he could probably lobby the government down with his trust fund.)

Evans, Downey Jr., Elizabeth Olsen and Chadwick Boseman also join the chat, teasing Black Panther’s MCU debut and Scarlet Witch’s involvement in the battle (she’s on Cap’s side) and her “emotional journey.”

In addition, EW continued the ongoing coverage from their special Civil War issue, releasing an interview with Sebastian Stan, reprising his role as Bucky Barnes / Winter Soldier. As we saw in the first trailer, Bucky’s involvement is a big component of Civil War, and Cap’s commitment to their friendship doesn’t help matters with Stark. Says Stan:

I think that’s one of the neat things about this movie and the third installment for Steve Rogers. We get to see another side of him. I mean you’d wonder, right? After so many years of being loyal and morally impenetrable and always doing the right thing that he wouldn’t somehow at some point go, “Man, like, what am I fighting for? What’s my life? What am I living for?” I think this movie very much tackles those questions for Steve Rogers. He’s been questioning things I think for a long time and this is where he’s deciding to follow his instincts and not what people tell him is right or wrong.

The actor adds that the film picks up almost immediately after Captain America: The Winter Soldier, and we’ll see Bucky evolve quite a bit:

This movie certainly deals with what’s happened to him. I mean, what have we gotten as a result of Bucky and the Winter Soldier? You know, here’s the guy when you merge the two. This is what came out. To me, he’s never really going to be Bucky Barnes again. There’s going be recognizable things about him, but his path through the [experiences of] Winter Soldier is always going be there, haunting him. He recognizes his past, but at the same time he’s sort of a new character, too.

It’s one of the greatest joys I have in playing this part because it’s like the three movies for me have been like three people, in a sense.

Captain America: Civil War hits theaters on May 6, 2016.
