Robert Downey Jr to return as Iron Man in Black Widow!

Robert Downey Jr. will reportedly return as Tony Stark / Iron Man in Black Widow, the next Marvel Cinematic Universe film centred on Scarlett Johansson's title character, also known as Natasha Romanoff.

[Spoilers ahead for the MCU.] If you're wondering how that's possible considering what happened to Iron Man in Avengers: Endgame, that's because the standalone Black Widow movie is a prequel — naturally, considering Romanoff shared the same fate as Stark. The extent of Downey Jr.'s role is unclear.

It's possible that he may not film any new scenes for Black Widow and will instead be shown through archival / previously unused footage, as has been the case for other Marvel stars and films in the past.
