With the final episode of The Falcon and The Winter Soldier just premiered on Friday. It appears things went really well because Marvel Studios have announced Captain America 4. It will be headed up by the head writer and show creator of The Falcon and The Winter Soldier, Malcolm Spellman will head up the movie and co-write the new script.
No announcement of the cast or story for the new movie. No announcement of a director at this time. It is unknown if Chris Evans will be a part of this film. It is expected that Anthony Mackie will return to continue his saga as the new Captain America. I suspect this movie will also star Sebastian Stan as Bucky Barnes but that is not confirmed.
