Joe Russo: "That’s not early in the film. But we felt like it was the cleanest way to draw a line and highlight that this is Captain America 3, and not Avengers 2 and a half. His memories are foggy. But he has them. He’s also different now. There’s a part of his personality that was under mind control, and he murdered a lot of people. So he’s got a very complicated history. Who is that person? How does that character move forward? He’s not Bucky Barnes anymore. He’s not the Winter Soldier anymore. He’s something inbetween."

Joe Russo: "When people leave the theatre, they’re going to be arguing about who was right in the movie, whether it was Tony, or whether it was Cap. Tony has a very legitimate argument in the movie that’s a very adult point of view, about culpability, about the Avengers’ responsibility to the world, and the world’s right to have some sort of control over the Avengers. It’s a very complicated emotional arc for Tony Stark in this movie. Downey is utterly amazing in the part. I think he’s taking this character he’s been crafting for years and goes to some very risky places in the movie with the character."

Joe Russo: "The theme of the movie is betrayal and it’s a very powerful theme. The movie’s extremely emotional. It hinges on that emotion, and on a very personal level we didn’t want the movie to become about politics and people arguing about platitudes. The third act is built around a very personal moment between these characters."

Yaaas. The Russo's always come through with movies that are actually about something instead of supers punching aliens and evil robots. Excited to see what they do with Infinity War.
Yass at this being CA3 and not A2.5 
Don't you remember SW trying to control Hawkeye's mind in AOU and he putting an arrow in her head?
