While Johansson's Black Widow was killed off in Avengers: Endgame before her own solo Black Widow movie, the actress had previously confirmed that she's in line to produce a mystery project for the MCU, though specifics have not been announced yet.
Confirmation for Scarlett Johansson Project
In an interview with Entertainment Tonight (ET) at the Las Vegas premiere of The Marvels, Marvel Studios president Kevin Feige officially confirmed that the studio is still in progress on an upcoming MCU project produced by Scarlett Johansson.
ET asked Feige about rumors that Johansson and Robert Downey Jr. may be making a return to the MCU, which Feige said was not discussed at the recent Marvel behind-the-scenes retreat. But, he did say that they are "doing a project with Scarlett," and that "in terms of returning, we'll have to see:"
ET: "Yeah, it was like one of the things that was talked about at this retreat were Scarlett Johansson and Robert Downey Jr. possibly returning at some point."
Feige: "We did not discuss that at the retreat. Is the truth. We're doing a project with Scarlett. I love Robert, he's a part of the family. But in terms of returning, we'll have to see."
What Could Johansson's Mystery Project Be?
Trying to speculate about the unknown project Johansson is producing is tricky, as there is truly almost no information about it.
Interestingly, those two characters, as well as the movie's antagonist Taskmaster, are set to appear in the upcoming Thunderbolts movie, which has been said to be a spiritual sequel of sorts to Black Widow.
Black Widow is currently streaming on Disney+.
