‘The Handmaid’s Tale’ and ‘The Square’ star Elisabeth Moss is set to produce and star as Rosemary Kennedy in director Ritesh Batra’s ‘A Letter From Rosemary Kennedy.’

Per Variety, the film is based on the 2016 Black List script by Nick Yarborough and explores “the little-known but haunting story of the eldest sister of President John F. Kennedy, who spent a lifetime hidden from public view because of the political ambitions of her father, Joseph Kennedy.”

Kevin Turen of Guy Grand Productions and Jason Michael Berman of Mandalay Pictures will produce the film alongside Moss. Executive producers include Allard Cantor, Richard Arlook, and Jarrod Murray.
