Who Killed Marilyn?

Who Killed Marilyn?

Who Killed Marilyn? A play that explores one of Hollywood’s unresolved mysteries: the death of Marilyn Monroe. The play invites the audience to become detectives, piecing together clues and questioning what really happened to the legendary actress, and the Emerald Theatre makes for the perfect backdrop. The Hollywood bulbs and signage out front set the scene for a vintage speakeasy transporting us straight back to the glitz and glamour of the 1950’s.

Pixie Lott gives a captivating performance as Marilyn, successfully capturing both the glamour of the Hollywood icon and the vulnerability hidden beneath her public image. Her portrayal goes beyond simply imitating Monroe’s famous appearance and mannerisms; she brings emotional depth to the role, allowing the audience to see Marilyn as a woman struggling beneath the weight of her celebrity. Lott’s star quality and confidence on stage are perfectly paired for such an iconic character, she gives all the sass while her more intimate moments reveal a softer and more fragile side. Her performance is particularly effective because it reminds the audience that behind the blonde hair, red lipstick and legendary status was a real person searching for security and happiness. Lott breaks down the fourth wall, winning over the audience from the very beginning as she takes them on a journey of discovery to finally solve the mystery and expose what is thought to be the biggest cover up in history.

The show is perfectly cast with the actors bringing distinct personalities and energy to the stage, giving the characters enough charm, tension and unpredictability to keep the mystery and suspense alive. Rather than relying on one standout performance, the production benefits from the chemistry between the cast, with each actor adding another layer to the unfolding story. However the production covers so much history, with every actor multi rolling and as the costumes are very similar it is easy to lose track of who is who and where you are in the timeline.

Sharleen Cooper Cohen's script and conspiracy material sometimes feels like it has been imported from a television documentary rather than transformed into drama. I find the premise intriguing but sadly undermined by a script that sometimes mistakes conspiracy for complexity. Several of the familiar allegations surrounding Monroe and the Kennedys have been circulating for decades, without the play necessarily finding a genuinely new theatrical language for them. Her play rehashes familiar conspiracy theories surrounding her 1962 death, including connections to the Kennedys and the mafia, without offering new insight. 

Despite Lott’s visual resemblance to the icon through signature styling, the play fails to reveal the woman beneath the public persona. Directed by Philip Wm McKinley, the production is a clichéd script and shallow portrayal of Monroe's complex personal life, reducing her struggles to superficial anecdotes about failed marriages and sexualized relationships. The snap shot performances, including depictions of Joe DiMaggio, Arthur Miller, JFK, and Bobby Kennedy, lack depth and clarity. You can see the creative vision and choices and it’s these layers that really shine through but a lot of the time they get lost in the pages and pages of factual text. The actors are great at making the comedic moments work well particularly alongside the darker elements, giving the audience opportunities to laugh while still maintaining the suspense of the storyline but sadly there is not enough of these moments leaving the audience desperate for some light relief. A good murder mystery should make you want to solve the crime before the characters do. There are enough suspicious characters and unanswered questions to make it difficult to settle on one explanation too early but with so many cross over’s and so much to squeeze in the piece, the suspects and scenario’s become disjointed and confusing.

The play largely ignores the formative experiences of Norma Jean, Monroe’s early identity, offering mere fleeting references to her trauma. The climax, featuring a contrived emotional revelation with her psychiatrist just doesn’t hit the mark. Ultimately, while the play provides a definitive answer to who allegedly killed Marilyn, it fails to meaningfully explore who she truly was, leaving her inner complexities untouched which is a shame because the production values and the cast are so strong, the creative choices are clever and with a better book the show could have exceeded expectations.

Overall, Who Killed Marilyn is enjoyable and offers a lot of information, a lot of which you don’t know. The production does a particularly good job of creating an atmosphere of suspicion. As different theories and possible suspects are explored, the audience is constantly encouraged to reconsider what they think they know. The uncertainty is one of the play’s greatest strengths, keeping the tension alive and making you want to discover the truth alongside the characters. Marilyn herself is presented as much more than a Hollywood icon. Yet the production's greatest strength is also its most frustrating weakness: Marilyn is more interesting than the mystery.

Whenever the play stops explaining the conspiracy and allows Lott simply to inhabit Monroe, the atmosphere changes and the famous face begins to disappear. It would have been nice to see a bit of Norma Jean, the woman before the photographs, before the husbands, before the presidents, before the endless cultural afterlife. Who killed Marilyn? Is the kind of show that gives you plenty to discuss afterwards, particularly your theories about who was responsible and whether you managed to spot the clues along the way?

This show was reviewed on the 20th August 2026 at The Emerald Theatre, London where it runs until the 29th October 2026. Tickets available here: Who Killed Marilyn? | Pixie Lott Play, Emerald Theatre London | Tickets
