Captain America director Joe Johnston has expressed interest in doing a Bucky solo film, quoted as saying "I told the Marvel guys that there is a character that I’m really interested in called ‘The Winter Soldier’ and that if, ‘you guys decide to make that picture I would definitely be interested.’ I just think that it would be interesting to take a character that was in ‘Captain America’ and build a story around him. Plus, I like Sebastian Stan a lot (who played Bucky) I think he would be an interesting actor to build another feature around." While no official word has been given, Johnston said that the film most likely won't happen until after Captain America 2, and has expressed interest in working with Scarlett Johansson and crossing over with her character of the Black Widow (Natalia Romanova). In the comics, Bucky and Black Widow have a romantic history dating back to the Cold War, and though Black Widow appeared in Iron Man 2, and the Cold War conflict was alluded to with Whiplash's treacherous father Anton Vanko, they did not develop any relationship between the Black Widow and the Soviets, leaving the possibility for it to be expanded, whether in a Winter Soldier or a Black Widow solo film. Though the film is only in the planning stages and has yet to start development, Sebastian Stan is signed on to reprise his role in a total of 6 Marvel films.
