"It's tricky."

That's Joe Russo's immediate reaction when asked how Avengers: Infinity War will top Captain America: Civil War, if such a thing is possible after he and his brother Anthony masterfully crafted one of the largest super hero blockbusters of all time in their dramatic brawler flick earlier this year.

"That's a great question," he goes on. "There could be a lot of pressure. We put pressure on ourselves, we feel the pressure. At the same time we have to be very zen and we have to step outside of that pressure because if you make decisions based on expectations and based on feeling that pressure, you're going to make bad decisions."

Stepping outside of the pressure cooker that is the ever-critical comic book movie fan community, Anthony and Joe Russo have the process and elements of a great movie down to a science.

"Ultimately, at the end of the day, the thing that we prioritize above all else is storytelling, and we just focus on the storytelling and the characters and how they fit into the narrative, and we just keep trying to tell the best story that we can every time out," Joe Russo explains. "That's all about the script work. There's an intense amount of script work that we put in. It's months and months spent in a room with us and with [Christopher] Markus and [Stephen] McFeely talking through the story, talking through the characters, turning over every stone, rewriting every scene, talking about whether this is the best line into a scene, best line out of a scene, is this the best execution of this scene, what else could the story be here."

"That's really where our focus and our effort goes," Joe Russo concludes. "We try to ignore any sort of external pressures because they can just lead you to a bad place creatively."

The Russo Brothers have a lot of story to tell with Avengers: Infinity War on the horizon. Not only will they be dealing with the ever-expanding Avengers line-up which now includes Brie Larson's Captain Marvel, Spider-Man, and Black Panther but the Guardians of the Galaxy will be joining the party.

Anthony Russo embraces the new faces, namely Chris Pratt's Star-Lord. "The movies are intended to be a culmination of everything that's happened before in the MCU so you don't want to get into spoilers but I'm a big fan of what James Gunn has done," Anthony Russo told Comicbook.com at a press event for Captain America: Civil War. "[Joe Russo and I] are both big fans of what James Gunn has done. Star-Lord is a fantastic character and Chris Pratt is an awesome performer so you'd be very excited."

Captain America: Civil War will be available for digital download on September 2 and on blu-ray/DVD on September 13. Avengers: Infinity War and the to-be-titled Avengers 4 hit theaters in 2018 and 2019, respectively.
