Marvel Studios has officially released a new featurette for its upcoming film Captain Marvel detailing the training that star Brie Larson has gone through to prepare for her role as Earth's Mightiest Hero.

The video features numerous clips of Larson's intense fitness training, the inner workings of the film's fight choreography and even a look at Larson's hands-on experience working with real-life Air Force pilots.

"Captain Marvel is about somebody who goes on a  journey of discovery," co-director Anna Boden said. "And I think it was really important for Brie to learn how to fight."

"By the time we started shooting I'd been training for nine months and I'm glad that I did," Larson added. "Doing fight sequences up and down a train for three months... felt kind of alive."

"The thing that I found so unique about this character was that sense of humor mixed with total capability in whatever challenge comes her way," she added. "Which I realized, after going to the Air Force base, is really what Air Force pilots are like."

"We simulated a dogfight. We were on offense, we were on the defense, we got to 6.5 Gs," Larson continued.

"It's a lot, a lot of work," Boden said. "She brings so much of that to the role. It's pretty awesome."
