The 25-year-old actress portrays Yelena Belova in "Black Widow", and she admitted the upcoming Marvel movie is so action-packed, it didn't take long before the two were forced to start getting physical with one another.
She said, "Within two days of knowing Scarlett, I was ramming her into a door frame or kitchen counter. It was the best way to get to know someone pretty quick - just fight them for a week."
Florence is convinced the fight sequences are some of the best yet seen in the comic book world, and she particularly loved working with so many women. The "Midsommar" star told TV and Satellite Week magazine, "I'm probably biased but I think there are some of the best fights we've had in the MCU."
"I've had all this time to build this physical vocabulary, and I'm finally able to use it all in this film. It was striking how many stuntwomen we had on set. The power of all these women in one room together was something I'd never experienced before."
She added, "It was an amazing feeling to be surrounded by all these bada** women and get down and dirty with them."
The Brit previously admitted she jumped at the chance to undertake another physical role after her experiences on "Fighting with My Family", the 2019 sports drama in which she played real life English professional wrestler Paige.
She added, "So, I love the stunts to this. It's probably my favorite part to this role and I fell in love with kind of like movement and action and stunts when I did... 'Fighting with My Family', so coming onto this I knew that it was intimidating, but I really enjoy it, and actually the stunt team are so excited when you want to do more. They really, really want you to do as much as possible."
