'Captain America 2,' dubbed 'The Winter Soldier,' was a major part of Marvel's Comic-Con 2013 panel presentation. The team has been busy filming the sequel, and, thanks to various buzzing paparazzi, we've already seen a ton of leaked photos from the set.

Following the events in 'The Avengers,' Chris Evans' Steve Rogers and Scarlett Johansson's Natasha "Black Widow" Romanoff team up to face a powerful yet shadowy enemy in present-day Washington, D.C., while the Cap is still trying to get his footing in this new world.

“Some people wanted to come say, hi,” said Marvel Studios President Kevin Feige before introducing co-directors Joe and Anthony Russo, and stars Frank Grillo, Emily VanCamp, Cobie Smulders, Anthony Mackie, Sebastian Stan, Samuel L. Jackson, Scarlett Johansson and Chris Evans.

“It’s getting better every time I put [the suit] back on,” said Evans. “It turns out, Marvel knows what they’re doing.” His character, Steve Rogers, is still adjusting to societal differences of the modern day.“The world we live in right now, it’s harder to know what’s right and wrong … some of the actions we take to prevent certain threats compromise some of our liberties.”

Black Widow is also very integral to ‘Captain America 2,’ said Johansson. “When we find these characters, it’s in real time … they’re really kind of partners.” Though we didn’t get to see much interaction between Cap and Widow, they now have this relationship. “This film is gritty. It’s got some down, dirty knuckle-bearing. … It’s got a lot of action in this one.”

“I’d say it’s kind of like an odd company. They each have different views on morality,” said Evans. “Dichotomies are sexy!”

As for Jackson, it feels “pretty badass” to throw on the eye patch again. He has a different relationship with everyone in the film, he says. “Some of the people they see as enemies are now comrades,” and Fury has to deal with that. Though, as he says, “everything he says is a lie.”

The story is pretty close to the original comic, said Feige, as far as the “Winter Soldier” goes. “In the movie, though, it’s a surprise to Cap and it’s Cap's conflict.”

“I have wings and guns. That’s all you need, right?” said Mackie. “We just handin’ out business. That’s what we do. ‘Captain America 2’!”

“You want me to show you guys why we hired them?" asked Feige before unveiling new footage: Things kick off with the Cap being ambushed in a glass elevator by Frank Grillo’s character and his team. Of course, even when things seem to almost go bad for Rogers, he turns it around and kicks ass. From there, the footage merges seamlessly with an extended trailer-like compilation, featuring Robert Redford, Johansson kicking ass, Mackie’s Falcon taking flight, Bucky Barnes’ newly-modified Winter Soldier uniform (bionic arm and all), and the S.H.I.E.L.D. station crashing into a body of water, ‘Star Trek Into Darkness’ style.

“S.H.I.E.L.D. is trying to find its place in this new world,” said Smulders. “There’s some new people coming on board … it’s basically trying to find ourselves in this new world.”

'Captain America: The Winter Soldier' stars Chris Evans, Scarlett Johansson, Samuel L. Jackson, Emily VanCamp, Sebastian Stan, Frank Grillo, Toby Jones and Robert Redford, and hits theaters on April 4, 2014.
