She further explained-
“I have to say—doing the stunt work—it’s not the day you’re shooting that’s most difficult. It’s all the hours you spend learning it. Once you’re shooting it, it’s definitely exhausting because of the repetition, but you’ve already gone through the most painful part of the process, which is learning the choreography of the fights.”
She even spoke about the hard work and patience that is involved in learning the art of fight sequences, she said-
“Especially because you have a tight timeframe to learn everything. If you’re lagging or there are things you’re unsure of, you just beat it into the ground until you get it. You have no choice.”
However, not many people know that Scarlett Johansson was not the first choice for the character of Black Widow. British actor Emily Blunt was approached by Jon Fraveau for the role, but due to a scheduling issue, the Oppenheimer star could never become a part of the Marvel Cinematic Universe.
