Biografia

Suffered from tracheomalacia as a kid, and got a tube in her trachea that helps her to breathe properly. This resulted in her having a unique, raspy voice.

Sings, writes her own songs and plays the guitar and piano.

Was unable to participate in the two-week-long rehearsal of Adoráveis Mulheres (2019), as she was filming Midsommar: O Mal Não Espera a Noite (2019). She said that the sudden transition from "Midsommar" to "Little Women" was very therapeutic, and has also stated that this helped create distance between her and her co-stars that played her sisters.

Other actresses, including her Adoráveis Mulheres (2019) co-star Saoirse Ronan, were considered for the role of Yelena Belova in Viúva Negra (2021). However, after Florence received positive reviews for her portrayal in Lutando Pela Família (2019), Marvel returned to her for the role.

Her audition for Abigail in The Falling (2014) was her first professional audition.

As an actor, it's very interesting to make the audience love you while you are doing horrendous things.

I really take my hat off to anybody that steps in the ring because it's so hard - you're competing against your friends, and you're working in front of an audience who tells you exactly what they're thinking.

I like a role where some of the character's motivations are confusing or at least interesting.

There's always going to be pressure, and there's always going to be an area where you disappoint. As a storyteller, you have to understand that.

It's always shocking when you see a modern woman in a period story line. It doesn't make sense.
