Sasha Pieterse Set to Portray Rosemary Kennedy in Upcoming Psychological Thriller

Sasha Pieterse is taking on a powerful new leading role. The 30-year-old Pretty Little Liars star has been cast to headline Rosemary, an upcoming psychological thriller that centers on the life of Rosemary Kennedy, the sister of President John F. Kennedy.

The film will present Rosemary Kennedy's narrative "from her perspective," offering an intimate portrait of one of the Kennedy family's most significant figures. Written and directed by Cory Todd Hughes and Adrian Speckert, the project draws inspiration from the All That's Interesting article titled "Rosemary Kennedy, JFK's Sister Who Was Lobotomized and Locked Away."

The thriller will chronicle Rosemary Kennedy's experiences with mental health, her father Joseph P. Kennedy Sr.'s decision to subject her to a lobotomy when she was 23 years old, and the enduring repercussions of that procedure.

Rosemary Kennedy was the sibling of President John F. Kennedy and U.S. Senators Robert F. Kennedy and Ted Kennedy. During her childhood and adolescence, she faced developmental difficulties and later contended with behavioral struggles. Following her lobotomy at 23, the procedure rendered her permanently disabled. She spent the majority of her remaining years in isolation at a Wisconsin facility before passing away from natural causes in 2005 at age 86.

Pieterse expressed her enthusiasm for the project in a statement, saying: "Rosemary's story has been told in fragments. What drew me to this project is how it explores her as a person, not a symbol, but a fully realized human being with dreams and vulnerabilities."

This casting marks Pieterse's latest screen venture, following a recent cameo appearance in a Meghan Trainor music video.
