Anthony Mackie and Sebastian Stan have played Falcon and Winter Soldier, respectively, for years now. As the two closest allies to Captain America, Falcon and Bucky Barnes attempted to help Cap take down Thanos in Avengers: Infinity War. Unfortunatley, they were turned to dust after the snap. Fans already know most of the heroes that "died" will be coming back somehow, and now, Falcon and Bucky have joined the list of confirmed survivors.
Among the already confirmed survivors are Spider-Man (Tom Holland just finished filming Spider-Man: Far From Home), Black Panther (Ryan Coogler will be returning to direct) and the Guardians of the Galaxy (whenever a new director is found). As reported by Varitey, Falcon and Winter Soldier will be teaming up for a limited series via the upcoming Disney streaming service. Malcolm Spellman (Empire) has been hired to write the show, which is still in the early stages of development. Tom Hiddleston's Loki has also been rumored to get his own series for the streaming service, which is gearing up to compete with Netflix. As Netflix begins to cut down on their Marvel content (Luke Cage and Iron Fist have both been canceled), Disney continues to stock up more Marvel heroes for their own service.
