Who Killed Marilyn? World Premiere Opens at the Emerald Theatre This Summer

The West End is set to welcome a tantalising new production this summer as Who Killed Marilyn? receives its world premiere at The Emerald Theatre. Running from Saturday 15 August to Thursday 29 October 2026, the play promises to blend Hollywood glamour with dark intrigue as it investigates one of the 20th century's most enduring mysteries: the circumstances surrounding the death of Marilyn Monroe.

Singer, songwriter, and actress Pixie Lott will take on the role of Monroe, marking another significant chapter in her growing stage career. Tickets for this hotly anticipated debut run are on sale now.

A Fascinating Story Brought to the Stage

Marilyn Monroe remains one of the most recognisable and written-about figures in modern history. From her meteoric rise as a Hollywood icon to her troubled personal life and untimely death in August 1962, Monroe's story has fascinated biographers, filmmakers, and conspiracy theorists for decades. While her death was officially ruled a probable suicide, questions about possible foul play have never fully subsided, fuelling countless books, documentaries, and now, a West End play.

Who Killed Marilyn? appears to tap directly into this rich seam of speculation and drama. Producer Tegan Summer has chosen London's Emerald Theatre as the venue for what is being billed as the production's world premiere. The Emerald Theatre, a newer addition to the West End landscape, provides an intimate yet prestigious setting for a show that will need to balance biographical detail with theatrical tension.

With a run stretching from mid-August through to the end of October, the production has a generous window to find its audience and build word-of-mouth buzz during one of London's busiest theatre-going periods.

Pixie Lott Steps Into Marilyn's Shoes

Pixie Lott is no stranger to the West End stage. She first made her mark in London theatre back in 2016 when she played Holly Golightly in Breakfast at Tiffany's at the Theatre Royal Haymarket. More recently, she appeared in Made in Dagenham at the London Palladium in 2024, further cementing her reputation as a performer who can command the stage as well as the recording studio.

Known for chart-topping hits such as "Mama Do" and "Boys And Girls" from her debut album Turn It Up, Lott has built a varied career spanning music, television, and acting. Her screen credits include Christmas Karma, Past Life, and McDonald and Dodd, while her television appearances as a judge on The Voice Kids and The X Factor have kept her in the public eye. She also released a studio album, Encino, last year.

Commenting on the role, Lott expressed her excitement: "I have always loved Marilyn. She is such a fascinating, timeless legend, and bringing her complex story to life on this beautiful stage is an absolute dream come true for me. I can't wait for audiences to experience the mystery, the glamour, and the raw emotion we will be pouring into this incredible play."

Playing Monroe is a formidable challenge for any performer. The role demands not only a physical transformation but the ability to convey the vulnerability, intelligence, and magnetism that defined the real woman behind the Hollywood persona. Given Lott's combination of musical talent and stage experience, it will be fascinating to see her interpretation.

The Supporting Cast

Lott will be joined by a strong ensemble of experienced theatre performers. Julie Armstrong, whose credits include Ballet Shoes at the National Theatre, brings classical training to the company. Benjamin Dilloway arrives from Pride and Prejudice at Regent's Park Open Air Theatre, while Ryan Ellsworth comes fresh from The Motive and the Cue, which played at both the National Theatre and the Noël Coward Theatre.

The cast also features Martin Hancock, known for Present Laughter on tour; Paul Kane; Rob Maloney, who appeared in A Clockwork Orange at the Soho Theatre; Henry Proffit from A Sherlock Carol at the Marylebone Theatre; and Mars Sams, who will be making his professional stage debut. Offstage covers include Joshua Ford, Eliot Giuralrocca, Dean Michael Gregory, Emma Haines, and Ricky Shah, ensuring the production has robust cover for its extended run.

While individual character assignments beyond Lott's Monroe have not yet been revealed, the cast's collective experience across straight plays, period drama, and physical theatre suggests a production that aims for dramatic depth rather than simple biographical pageantry.

Why This Production Matters for the West End

The arrival of Who Killed Marilyn? is notable for several reasons. World premieres of new plays in the West End carry a particular thrill, offering audiences the chance to see a story unfold on stage for the very first time. Unlike transfers from regional theatres or Broadway imports, a world premiere means that London audiences are the first to pass judgement.

The show also taps into the current cultural appetite for true crime and historical mystery. From podcasts to streaming documentaries, the public's fascination with unsolved cases and hidden truths has never been greater. A theatrical take on Monroe's death, staged with all the spectacle and emotional immediacy that live performance allows, could prove to be exactly the right show at the right time.

The Emerald Theatre provides a compelling setting. As one of the West End's newer venues, it offers modern facilities and production capabilities that can support ambitious staging. For a play that needs to evoke 1960s Hollywood, the Kennedy-era political world, and the shadowy corridors of power, the right venue makes all the difference.

What We're Watching For

Several questions remain ahead of the opening night. The creative team behind the production, including the playwright, director, and design team, have not yet been fully detailed in the initial announcement. These details will be crucial in setting expectations: is this a straightforward biographical drama, a thriller with noir influences, or something more experimental?

The title itself, Who Killed Marilyn?, suggests the production will lean into the conspiracy and mystery elements of Monroe's death rather than offering a conventional life story. This positions it as more of a dramatic investigation than a tribute show, which could make for compelling theatre if the writing is sharp and the performances are strong.

We'll also be watching to see how the production markets itself during the busy autumn season. With so many shows competing for attention across London's theatreland, a new play needs a strong hook to cut through the noise. The combination of Pixie Lott's star power and the enduring fascination with Marilyn Monroe should provide that, but sustained success will depend on reviews and audience response once the curtain goes up.

Should You Book?

If you're drawn to true crime narratives, Hollywood history, or simply enjoy the excitement of being among the first to see a brand-new production, Who Killed Marilyn? deserves a spot on your radar. The casting of Pixie Lott adds genuine star appeal, and the subject matter is rich with dramatic potential. A world premiere always carries an element of the unknown, and that sense of discovery is part of what makes live theatre so special.

The run from 15 August to 29 October gives plenty of flexibility for booking, though early performances may offer the best availability. With the West End's autumn season shaping up to be particularly vibrant, this is one of the more intriguing additions to the calendar.
