Whedon said that he is drawn to Black Widow's grounded nature as compared to other out of this world heroes like Thor and Vision. "When you get into your Superman territory it's harder to maintain that sort of gritty action that the Russo brothers do so beautifully," said Whedon. "I'd really do a spy thriller. Like really do a good paranoid sort of John Le Carre on crack kind of thing. That would be really fun.
He has praised Scarlett Johansson's portrayal of the character, calling the actress "just delightful."
Whedon famously clashed with Marvel after the release of "Age of Ultron," discussing publicly the disagreements he had with the studio over what would and would not be included in the final version of the film. He had also previously stated that he was done with Marvel movies entirely.
However, in April, he said he regretted his comments, and any bad blood between him and Marvel has dissipated enough that he would be willing to partner with the studio again.
Scarlett Johansson's Black Widow is one of the few main Avengers who has yet to get a solo film, despite the actress' huge earning potential. Last month Johannson was recently named the highest-grossing actress of all-time.
