Francesca Scorsese grew up around film. Every Saturday, she and her dad, Martin Scorsese (ever heard of him?), would watch classic movies together, and she clocked her 10,000 hours on set before most.

Now 20, with her roles as “Little Girl” in The Aviator, The Departed, and Boardwalk Empire behind her, she’s stepping into her own as Britney, a self-assured, super-social character with pink hair in Luca Guadagnino’s gorgeous, angsty coming-of-age series We Are Who We Are, which premiered on HBO last month.
