Netflix has set the stage for The Thursday Murder Club’s big-screen debut with a charming, week-long partnership with the Royal Horticultural Society to celebrate the film’s release. The cozy-crime adaptation of Richard Osman’s best-selling novel, directed by Chris Columbus (Home Alone), arrives in UK cinemas on August 22 and streams on Netflix from August 28. The ensemble cast features Helen Mirren, Pierce Brosnan, Ben Kingsley, and Celia Imrie.
To mark the launch, RHS gardens across the UK will host Murder Amongst the Marigolds from Friday August 22 to Thursday August 28. Visitors can take part in themed scavenger hunts that blend horticulture with homicide, explore floral billboards inspired by the film, and, at RHS Garden Wisley, enjoy a special afternoon tea at Joyce’s Tearoom. The menu nods playfully to the club’s members, including Elizabeth’s Earl Grey (with a twist), Ibrahim’s calming chamomile, Joyce’s celebrated lemon drizzle, and Ron’s must-try sausage rolls.
Participating locations:
– RHS Garden Wisley, Surrey
– RHS Garden Bridgewater, Manchester
– RHS Garden Harlow Carr, North Yorkshire
– RHS Garden Hyde Hall, Essex
– RHS Garden Rosemoor, Devon
The film follows four spirited retirees who pass their days solving cold cases for fun—until a real murder lands on their doorstep. Osman has noted the screenplay is inspired by the first book but not identical, a practical choice to make the story work on screen. He’s praised the team behind the film, including Amblin and Netflix, and the star-studded cast under Columbus’s direction.
Additional comments and context
– The RHS collaboration is a smart, on-brand extension of the series’ cozy-crime appeal—inviting fans to step into a gentle, puzzle-filled world that suits a garden setting. It’s an accessible way to build buzz while giving families and book clubs a late-summer activity tied to the film.
– Expect the movie to balance the warmth and wit of the books with streamlined plotting for cinema. Small changes are typical in adaptations and often help maintain pace while preserving character charm.
– If you plan to attend the RHS events, check the RHS website for schedules, availability, and any booking details, as the activation runs for one week only.
