Sing Street star Lucy Boynton has been cast in a key role opposite Naomi Watts in Netflix’s upcoming drama series Gypsy.

The series follows the journey of Jean Holloway (Watts), a therapist who begins to develop dangerous and intimate relationships with the people in her patients’ lives. Boynton will play Allison, a 19-year-old patient of Jean’s (Watts). She has recently dropped out of school to support her addiction and is hiding this secret from her mother.

Boynton, who received critical praise for her performance as the aspiring model in Raphina John Carney’s Sundance buzz title Sing Street, will next be seen in Osgood Perkin’s I Am The Pretty Thing That Lives In The House, which recently premiered at Toronto, and Danny Strong’s Rebel in the Rye, opposite Nicholas Hoult and Kevin Spacey. Boynton also was recently cast in Fox’s re-imagining of Agatha Christie’s Murder on the Orient Express, to be directed by Kenneth Branagh. She’s repped by CAA and United Agents.
