Ratched has just started airing on Netflix and the series tells the story of how Nurse Mildred Ratched (played by Sarah Paulson) came to be one of the eeriest TV villains. The show is set in the late 1940s and it gives insight into what happened to Nurse Ratched as a child. Rosanna Arquette plays an important role in Ratched's backstory, and Express.co.uk has everything you need to know about who the actress plays.
Rosanna Arquette is an American actress and film director who has won a number of awards for her film roles.
The 61-year-old actress, from New York City, is known for her roles in The Executioner's Song and Desperately Seeking Susan.
Her other memorable roles were in Pulp Fiction and Crash, and she directed documentaries including Searching for Debra Winger.

Ratched fell into a trace and believed the host of the show was telling her life story about how she was an orphan.
She and Edmund Tolleson (Finn Wittrock) had both been fostered by the same family, but their foster parents were abusive.
They returned to their caseworker, Anna, who took pity on them and found them a new home, but again they were abused.
Arquette plays the kind caseworker in the series, and she is a recurring character who appears throughout the flashbacks.
Wanting to make sure Ratched and Edmund stayed together, she forged a letter explaining how they were biological siblings.
