Speculations

Marylebone Theatre

Opened Nov 5, 2026 · Closes Jan 17, 2027

Critics' Take

Critics find this conspiracy thriller about Marilyn Monroe and JFK's deaths dull and clunky despite an intriguing premise. Janie Dee's performance earns praise, but most dismiss Torben Betts' script as formulaic and dramatically inert.

“The highly accomplished Dee is always a joy to watch but Gloria Obianyo as Flo is more than her match as the calm though curious wannabe journalist, the perfect contrast to Kilgallen’s star status, paranoia and increasingly drunken state.” By Clare Brotherwood, Nov 5

“Overall, a very glossy production, superbly performed with seriously intriguing content that will grip you all the way through.” By Phil Brown, Nov 5
