Marvel and Disney aren’t ready to discuss the project yet, but sources told Entertainment Weekly in April it is now in development along with a show pairing Sebastian Stan’s Bucky Barnes (a.k.a. The Winter Soldier) and Anthony Jackie’s high-flying Falcon, and another focused on the trio of Tom Hiddleston’s Loki, Elizabeth Olsen’s Scarlet Witch, and Paul Bettany’s The Vision.
