Grand Slam Sequel Confirmed: Mike Bubbins and Steve Spiers Team Up for Iconic Welsh Rugby Reboot

Welsh comedy heavyweights Mike Bubbins and Steve Spiers have officially secured the screenplay rights to write a highly anticipated sequel to Grand Slam, the legendary 1978 Welsh rugby comedy. Making the announcement on the latest episode of the Socially Distant Sports Bar podcast on May 19, 2026, the duo confirmed that legalities have been finalized with the original IP holders. However, rather than retreading old ground with a lazy modern remake, the upcoming feature film aims to deliver a fiercely authentic homage to the heart and hiraeth of Wales’ most enshrined cultural masterpiece.  

Grand Slam 2 Release Date, Cast, and Everything We Know So Far

While an exact theatrical release date has not been officially announced yet, script production is actively underway following the successful acquisition of the screenplay option in May 2026. The project is being co-written by Mammoth creator Mike Bubbins and veteran Welsh actor Steve Spiers (The Tuckers, Stella). The creative team is explicitly designing the narrative around a modern-day setting while tracking down surviving members of the original 1978 cast—which famously starred Windsor Davies, Sion Probert, and the late Dewi "Pws" Morris—to bridge the generational gap. The film will secure traditional theatrical distribution across Wales and the UK, with streaming rights to be finalized upon completion of the script.  

Full Plot Breakdown

The structural foundation of the Grand Slam sequel is engineered to honor the exact DNA of the 1978 original, which followed a chaotic, beer-fueled weekend excursion of a Welsh rugby union club flying to Paris to see Wales play France for the Five Nations title.  

The Pitch Document and the Creator's Daughter

The journey to securing the sequel rights began with a deeply personal connection. Mike Bubbins and Steve Spiers, self-described as the world's biggest Grand Slam fans, sat down to draft an elaborate pitch document detailing how a modern-day continuation would operate without compromising the original film’s untouchable legacy.  

During an initial production meeting with the rights holders, a studio executive asked the pair why they specifically wanted to tackle Grand Slam. When Bubbins expressed his deep, lifelong love for the movie's unique Welsh hiraeth (a deep homesickness or nostalgic longing for Wales), brilliant script layout, and iconic characters, the executive smiled and revealed a stunning detail: her late father, Gwenlyn Parry, was the legendary screenwriter who wrote the original 1978 masterpiece. This instant emotional alignment cleared the path for the option to be paid and the legal parameters to be locked.  

Setting the Story in the Modern Professional Era

The narrative backbone of the new script transitions away from the amateur 1970s "Golden Era" of Welsh rugby into the complex, often chaotic reality of the modern professional game. Bubbins and Spiers have made it strictly clear that the film will not be a mechanical remake, as the original is considered flawless.  

Instead, the plot explores what a classic Welsh rugby club outing looks like today. The story targets the lighter, deeply humorous side of contemporary fan culture, utilizing sharp situational comedy to contrast old-school rugby traditions against the structured, corporate reality of the modern game. Spiers is actively handling keyboard duties to flesh out the dialogue, ensuring that the working-class wit and regional banter perfectly mirror the character-driven chemistry that made the original a massive cult classic.

Post-Credits Scene / Future Live Stage Adaptation

The corporate and creative strategy behind the Grand Slam reboot extends far beyond a single feature film. Alongside the screen rights secured by Bubbins and Spiers, a parallel live theatrical stage play adaptation is currently in development.

While specific post-credits or sequel setups remain strictly unwritten ahead of the final screenplay draft, the dual-media expansion strategy ensures that the Grand Slam universe is being built for long-term cultural endurance. If the film successfully captures the nostalgic magic of Welsh match-day culture, it establishes a fresh commercial template for localized UK sports comedies aimed directly at dedicated regional audiences.
