Broadway’s longest-running satire is pulling off a historic reunion: for its 15th anniversary, The Book of Mormon will host a first-of-its-kind “Magical Mormon Mystery Week” featuring original stars Josh Gad and Andrew Rannells alongside its creators—a move that directly answers years of fan campaigning for a canonical cast return.
The announcement arrived on a late-night couch: during a March 16 appearance on The Late Show with Stephen Colbert, The Book of Mormon creators Trey Parker, Matt Stone, and Robert Lopez revealed a milestone celebration unlike any Broadway has seen. To mark 15 years, the nine-time Tony Award winner will bring back its original Broadway leads for a special week of performances this June—a direct response to persistent fan demand for an official reunion according to the show’s official site.
- The “Magical Mormon Mystery Week” runs June 9–14, 2026, at the Eugene O’Neill Theatre, with original cast members performing select scenes alongside the current company.
- Original stars returning include Tony-nominated leads Josh Gad (Elder Cunningham) and Andrew Rannells (Elder Price), alongside Nikki M. James (Nabulungi) and Rory O’Malley (Elder McKinley).
- Creators will appear throughout the week, with Parker, Stone, and Lopez also making special guest appearances.
- A reissued 15th anniversary cast recording will release June 26 on vinyl and CD via Ghostlight Records, featuring new commentary and behind-the-scenes content.
The scale of the event is unprecedented. For one week only, no two performances will be identical as original and current cast members share the stage. This “mystery” format—where surprises are baked into every show—represents a bold experiment in theatrical event-making as detailed by People. It also marks the first time Broadway has staged a reunion week of this magnitude for any musical.
Why does this matter? For over a decade, The Book of Mormon has existed as a cultural touchstone—a sharply satirical yet heartfelt musical that redefined what Broadway comedy could achieve. Its original cast recording won a Grammy, and the show remains the longest-running production in the 100-year history of the Eugene O’Neill Theatre, having broken its own box office records repeatedly. It currently ranks as the 10th longest-running Broadway musical of all time, with productions spanning London’s West End and tours across three continents.
The original cast—Gad, Rannells, James, and O’Malley—became overnight stars, but their schedules have rarely aligned for official reunions since 2011. Fan forums and social media have long buzzed with “what if” scenarios about a full-circle return, making this “Mystery Week” a direct answer to that collective wish. By staging this during a regular performance week rather than as a limited engagement, the producers are also testing a new model for milestone celebrations—blending nostalgia with the show’s ongoing life.

Complementing the onstage events, the Grammy-winning original Broadway cast recording will receive a deluxe 15th-anniversary reissue on June 26 through Ghostlight Records. The releases—available on crystal-clear vinyl, black vinyl, and CD—include a lyric booklet, production photos, and new audio commentary from Parker, Stone, and Lopez in conversation with music supervisor Stephen Oremus and journalist David Pogue. This archival push ensures the anniversary resonates beyond the theater, offering longtime fans new behind-the-scenes insight.
The celebration extends to the show’s official 15th anniversary date, March 19, 2026, with audience giveaways and surprise appearances expected during that performance. Tickets for all shows, including the “Mystery Week” dates, are currently available via the show’s official ticketing partners.
What makes this announcement particularly resonant is its timing. In an era where legacy franchises often rely on revivals or film adaptations, The Book of Mormon is choosing to deepen its stage legacy by reactivating its original creative DNA. The involvement of Parker and Stone—whose South Park sensibilities defined the show’s comedic voice—alongside composer Robert Lopez (of Avenue Q and Frozen fame), guarantees that any new material or commentary remains authentic to the show’s founding spirit.
This move also sets a precedent for other long-running shows. By notching a “first” for Broadway with a cast reunion week, The Book of Mormon is essentially writing a playbook for how to celebrate a milestone without disrupting the show’s continuity. The “mystery” element keeps even the most devoted fans guessing, transforming each performance into a potential historic moment.
For a generation that discovered the show through its cast recording or touring productions, the return of Gad and Rannells—both now household names from film and television—creates a bridge between the show’s Off-Broadway roots and its current cultural footprint. Their participation signals that the original vision remains sacrosanct, even as the company evolves.
The fan community’s reaction has already been electric, with social media erupting in speculation about which songs might feature additional harmonies or which scenes might be expanded. This isn’t merely a nostalgic cash-grab; it’s a strategic investment in the show’s lore, reinforcing that The Book of Mormon is more than a collection of jokes—it’s a living piece of theater history willing to revisit its origins.
As Broadway continues its post-pandemic recovery, events like this serve as vital reminders of the theater’s unique power to create shared, time-bound experiences. You cannot stream “Mystery Week”; you must be in the room where it happens. That exclusivity, paired with original cast appearances, makes these June performances among the most sought-after tickets of the decade as noted by ticketing partners.
Ultimately, The Book of Mormon‘s 15th-anniversary strategy succeeds because it respects both the show’s past and its present. It doesn’t just look backward; it integrates the original artists into the ongoing narrative, creating a living timeline that fans can experience in real time. This is how you honor a milestone—not with a static plaque, but with dynamic, unpredictable stage magic.
