Scarlett Johansson
After debuting as the Black Widow in 2010’s ‘Iron Man 2’, Scarlett Johansson’s assassin-turned-hero became a staple of the MCU.
Even so, once the character met her end in 2019’s ‘Avengers: Endgame’ and then had her own solo outing a year later, the actress has insisted she “has no plans” to return to the role.
She said: "I feel really satisfied with this film [‘Black Widow’]. It feels like a great way to go out for this chapter of my Marvel identity."
