Marvel has scheduled reshoots for Captain America: The Winter Soldier starting next week. It isn't yet clear which cast members will be back for the additional photography, or what new story elements are being worked into the screenplay.

Shooting will take place on December 16 and December 17, before going on break for the holidays. Everyone involved will then resume work in January for two more weeks. As of now, it isn't known where this additional photography will take place.

Reshoots have become commonplace on Marvel Studios productions, and practically every big-budget shoot, for that matter. Marvel went back for reshoots on both of this year's blockbusters Iron Man 3 and Thor: The Dark World, the second of which had additional scenes involving Loki (Tom Hiddleston) added.
