Exploring Rosemary Kennedy’s Story
Rosemary Kennedy, the sister of John F. Kennedy, Robert F. Kennedy, and Ted Kennedy, exhibited developmental challenges from childhood and behavioral issues in adulthood. At 23, her father, Joseph P. Kennedy Sr., decided to have her undergo a lobotomy, which left her permanently disabled. After the procedure, she spent most of her life at St. Coletta in Wisconsin, away from her family, until her death in 2005 at the age of 86.

The Film’s Perspective
The film aims to present Rosemary’s story from her perspective, focusing on themes of autonomy, dignity, and identity. Sasha Pieterse expressed her interest in the project, stating, “The story of Rosemary has been told in fragments. What attracted me to this project is how it explores her as a person, not as a symbol, but as a fully realized human being with dreams and vulnerabilities.” The directors emphasized that the film is not just a historical biopic but a psychological thriller centered on Rosemary’s inner journey.
Production Details
The film is produced by Mike Medavoy, Emanuele Moretti, and The Motus Studios, with involvement from Nick Medavoy and Kaan Karahan. It is written and directed by Cory Todd Hughes and Adrian Speckert. The project seeks to shed light on a story that has long been in the shadows, placing Rosemary at the center rather than as a footnote in a political dynasty.
