The "Sherlock" actor first played the CIA operative, who had been tasked to control and regulate the actions of the Avengers, in "Captain America: Civil War" - and returned for 2018's "Black Panther".
Director Ryan Coogler has signed on for the follow-up, but further details are currently unknown. However, in a chat with Collider, the British actor let slip he will be back for the sequel.
"As far as I know, I will be returning," he shared. "As far as I know, I will be in another Black Panther. That's my understanding. As to when that will happen, I don't know."
It isn't known when the sequel will be released but, as it didn't appear on Marvel's slate for 2020 and 2021 during their San Diego Comic-Con presentation, it's likely it won't debut until at least 2022.
Last year, Marvel boss Kevin Feige told Entertainment Weekly the plot for the sequel was coming together.
"One of the favourite pastimes at Marvel Studios is sitting around on a Part One and talking and dreaming about what we would do in a Part Two," he told the news outlet. "There have been plenty of those conversations as we were putting together the first 'Black Panther'. We have ideas and a pretty solid direction on where we want to head with the second one."
