While Johansson will, indeed, be returning to the part of the supremely trained agent in Black Widow next year (after Natasha sacrificed herself in Avengers: Endgame), SNL gave Johansson a chance to (somewhat) bring the character back to (sort of) battle Pete Davidson’s Thanos.
Scarlett Johansson, of course, is best known for her long-running role as Black Widow (real name Natasha Romanoff) in the Avengers film franchise, as well as three other MCU movies since 2010.
