Cast and creatives
The new play from Torben Betts explores three deaths that shook America –Marilyn Monroe, John F. Kennedy and Lee Harvey Oswald – and one woman who refused to stop asking questions. It is New York, 1965, and Dorothy Kilgallen is on the trail of the biggest story of her career, but the closer she gets to the truth, the more dangerous the questions become. When the threats reach inside her own home, she must decide how far she is prepared to go to tell a story some very powerful people would rather remain untold.
The complete cast for the world premiere includes:
- Janie Dee as Dorothy Kilgallen
- Jolyon Coy as Bobby
- Natalie Dunne as Norma Jean
- Gloria Obianyo as Flo
- Joseph Potter as Lee
- Ferdy Roberts as Carlos
Director Trevor Nunn leads a creative team that includes design by Lee Newby, lighting design by Johanna Town and sound by Gregory Clarke.
