The writing was on the wall since Avengers: Endgame and it took Falcon and the Winter Soldier to really get us there but Anthony Mackie has officially signed on to star in the untitled fourth Captain America film, according to Deadline.
By no coincidence, the fourth Captain America film was revealed to be in development, with writers Malcolm Spellman and Dalan Musson penning the script, at the tail end of the FATWS finale. While none of this is surprising, that the deal has been signed and closed is very exciting. There’s no word on whether his co-star Sebastian Stan makes the cut in this film. Deadline is also noting that this film isn’t the same MCU project that Chris Evans signed for earlier this year.
