Producer Kevin Feige has previously discussed how he wanted the upcoming Marvel Phase Two sequel Captain America: The Winter Soldier to have the same tone as a 1970s political thriller. Today, we have a new featurette, where the Marvel executive reveals how films of that era such as Three Days of the Condor and All the President's Men lead to the casting of Robert Redford as Alexander Pierce. The actor himself revealed that the elements of mystery were what appealed to him in taking on the role, with directors Joe Russo and Anthony Russo explaining that Pierce is the head of the World Security Council. Samuel L. Jackson also reveals that an actor of Robert Redford's stature brings more gravitas to the sequel, which arrives in theaters April 4. Check out the video, then read on for more details from Kevin Feige about how Captain America: The Winter Soldier leads into Avengers: Age of Ultron, and a shot of Captain America's "to-do list" featured in the South Korean version of the film.

During an interview with JoBlo, producer Kevin Feige teased how Captain America: The Winter Soldier ties into Avengers: Age of Ultron. He revealed that the 2015 sequel serves as both a continuation of Captain America's story and The Avengers as a whole, teasing that Cap will ponder a new line of work.

"I don't want to give too much away but it is very much a continuation of this story line and sort of going back into The Avengers fold. Steve is now torn between is he just a soldier? You know there is a scene in Winter Soldier where Anthony Mackie asks, 'Well what would you want to do if you are not a soldier anymore?' and part of his journey in The Avengers is to answer that question."

He also commented more on the possibility of doing a new Hulk movie with Mark Ruffalo, reiterating his previous statements that both the Green Goliath and Hawkeye (Jeremy Renner) have bigger roles in Avengers: Age of Ultron.

"I would love to do [Incredible Hulk 2] with Mark Ruffalo. But part of the fun of Age of Ultron was saying, you've seen another Iron Man adventure before, you see another Thor adventure and another Cap adventure, but we haven't seen the Green Goliath again. So that was important in the characters you haven't seen - Hulk being one of them and Hawkeye being one of them - Ultron will make up for it. They have very big parts in Age of Ultron."

While Kevin Feige has an integral role in the massive creation of the Marvel Cinematic Universe, Avengers: Age of Ultron director Joss Whedon plays a major part in how all the films are crafted as well. When asked which one has more control over the direction of this sequel, Kevin Feige had this to say.

"Both. It really is both. The only way we can work is with a very, very intense collaboration. And I think Joss was aware of that when he signed up for us the first time. It's still the case this time. But to his credit, he hasn't said, I directed the third highest grossing movie of all time, I don't need anybody. He is very, very collaborative and he is also very, very, very good. Just like the Russo's and like James Gunn right now on Guardians of the Galaxy. We are very lucky to work with people that are so collaborative with us and can elevate our initial idea. Even to elevate something in the way that we weren't expecting. That's their job and the best of them are able to do that very, very well. There are things that Joss is doing in Age of Ultron that will be amongst the best elements that we've ever brought to the screen."

In one final bit of Marvel news, we reported yesterday that Captain America: The Winter Soldier's U.K. release will feature a different version of Cap's "To-Do List," which consists of pop culture items he has missed over the past 70 years since he was frozen in ice. Today, we have word that the South Korean version of the sequel will have its own unique list, featuring cultural touchstones such as Dance Dance Revolution, local soccer hero Ji-sung Park, the 2002 World Cup which was held in Seoul, South Korea and the original Chan-wook Park classic film Oldboy. Check out how the South Korean version compares to the U.S. and U.K. lists below.
