In Captain America: The Winter Soldier, directors Joe and Anthony Russo bring Marvel’s patriotic do-gooder into the modern age. The DVD/Blu-ray of the blockbuster sequel goes on sale Sept. 9 and Yahoo Movies has an exclusive preview of one of the behind-the-scenes featurettes above — this one about Cap’s evolving fighting style. We also spoke to the brother directing team about their upcoming TV gig and the question everybody wants an answer to: What do they have planned for Captain America 3?

Before turning their attention to the next feature, the Russos are directing several episodes of the spin-off TV series Agent Carter, debuting on ABC in January 2015. The miniseries follows the solo adventures of Peggy Carter, the love of Captain America’s life and founder of S.H.I.E.L.D. in the 1940s. From there, the brothers will tackle the third film, which picks up “a couple years” after Winter Soldier left off. Although the heart of the movie will be Steve Rogers’ complicated relationship with his childhood friend Bucky Barnes, the themes of politics and power will still be in play. “The character was invented for an explicitly political purpose. So it’s hard to get away from that nature,” Anthony tells Yahoo. It’s also important to the directors that Captain America doesn’t become another disillusioned antihero. As Joe sees it, “his morality is part of his superpower.”

While they’re not leaking any major details from the 2016 film, the Russo brothers promise that they’re “bringing some new elements to the table that will give us a twist on Winter Soldier.” Does this mean that Steve Rogers will pass the Captain America shield to Bucky Barnes (aka the Winter Soldier) or Sam Wilson (aka the Falcon), both of whom have donned the stars-and-stripes in the comics? With actor Chris Evans shifting his focus to directing, and Sebastian Stan and Anthony Mackie already in place as the Winter Soldier and the Falcon respectively, the next film could allow a new hero to step in.

The directors won’t say either way, but the one spoiler they did give was that a certain group of people will definitely make a cameo appearance: the Russos’ children, parents, and other relatives, who show up in all their films. “If you look at the credits of Winter Soldier,” says Joe with a laugh, “there’s probably 47 Russos in the film.”
