Director Julius Onah recently opened up about the uncredited appearance of fan-favorite Sebastian Stan in the movie, who turned up for a single scene as Bucky Barnes ahead of his more prominent role in May’s release of Thunderbolts*.

So Bucky Barnes appears and reunites with Sam Wilson in Captain America: Brave New World, but what happens in their one scene together? Bucky arrives to comfort Sam at one of his lowest points in the movie.

There's a very good chance the asterisk in the title of Thunderbolts* indicates a certain prominent MCU character will appear.
