Scarlett Johansson has made it clear that her time as Black Widow in the Marvel Cinematic Universe (MCU) has come to an end. In a podcast interview with Gwyneth Paltrow, Johansson stated that she feels she has done everything she needed to with the character. However, her character's sister, Yelena Belova, played by Florence Pugh, has the potential to take on the mantle of Black Widow in future MCU projects. Yelena's connection to other characters like Bucky Barnes suggests she could become an important figure in the next phase of the MCU.
