Abigail Barlow and Dylan Mulvaney join 2026 Broadway cast of Six

New casting has been announced for Broadway’s Tony Award–winning musical Six, with Grammy winner Abigail Barlow and performer Dylan Mulvaney joining the 2026 company at the Lena Horne Theatre.

Beginning February 16, Mulvaney will make her Broadway debut in the role of Anne Boleyn, while Barlow will join the production as Katherine Howard. The updated cast also includes the return of two original Broadway performers, reinforcing the show’s continued popularity more than four years after its Broadway opening.

Adrianna Hicks will reprise her role as Catherine of Aragon, which she originated on Broadway, while Olivia Donalson returns as Anna of Cleves and Anna Uzele resumes her role as Catherine Parr. A casting announcement for Jane Seymour has not yet been made. Current alternates Aryn Bohannon, Sierra Fermin, Nicole Kyoung-Mi Lambert and Aiyana Smash will remain with the production in their respective roles.

Mulvaney is a writer, performer and digital creator known for her Off-Broadway solo show The Least Problematic Woman in the World and her viral TikTok series Days of Girlhood. Her work spans music, comedy and live performance across the United States.

Barlow rose to prominence as one half of the Grammy-winning duo behind The Unofficial Bridgerton Musical Album. Her recent projects include contributing music to the animated feature Moana 2, along with releasing solo music as a recording artist.

The current Broadway cast will give its final performance on February 15. Six originally opened on Broadway in October 2021 and reimagines the six wives of Henry VIII as contemporary pop stars. The musical won the 2022 Tony Award for Best Original Score and continues to be one of Broadway’s highest-grossing productions.
