"Captain America: The Winter Soldier" stars Anthony Mackie (The Falcon) and Sebastian Stan (Winter Soldier) both attended a panel at Wizard World Chicago Comic-Con over the past weekend. As a tease, Mackie offered his personal take on the plot details of "Captain America 3".

Movieweb reports that during the question & answer session, Mackie claimed the third movie installment would involve a team up between Captain America and Falcon. Both would be on a mission to get Bucky Barnes (The Winter Soldier) back to the good side, which means having him as Steve Rogers friend again. Mackie claimed Cap and Falcon would go look for Winter Soldier together and when they find him, they go through this "traumatic ordeal" of transforming him back to Bucky.

Additionally, once the Winter Soldier is out and Bucky is back in, the trio would form a three-man army to defeat evil.

"We become a three-man duo -- he's got a shield, he's got an arm and he's got wings -- and we go out and we save the world," Anthony Mackie said during the panel.

However, as seen on the video below, the actor was clearly joking according to the site. Suffice to say that Disney and Marvel has yet to really reveal or confirm the actual plot details for "Captain America 3". One thing though that co-directors and brothers Joe and Anthony Russo confirmed, is that the movie will be the end of Chris Evans role as Captain America.

In an interview with Collider, the brothers revealed the ending for "Captain America 3".

Falcon will eventually "take over the mantle" from Captain America at the end of the movie, says Joe Russo. The director even let slip that Bucky may have a chance of becoming the next super soldier when he mistakenly said "Bucky takes over the mantle at the end of Cap 3."

Aside from looking into Cap's possible successor, Joe Russo also hinted at Frank Grillo's (Crossbones) return in "Captain America 3".

"He's not alive at the end of Winter Solider for no reason, so let's just say that," he said.

As previously mentioned by International Business Times, Joe and Anthony Russo will also bring in new greater villains to "Captain America 3," which will reportedly bring out a more powerful hero in Steve Rogers.
