Kenrex is a true-crime thriller play that dramatizes the real-life events surrounding the 1981 killing of Ken Rex McElroy in Skidmore, Missouri. It's co-written by Jack Holden and Ed Stambollouian. It also features an original score by John Patrick Elliott. It had its world premiere at the Tanya Moiseiwitsch Playhouse in Sheffield in October 2024.
The play is set in the rural town of Skidmore, Missouri, during the late 1970s and early 1980s, a period of economic decline for the local farming community. The narrative centers on the reign of terror led by Ken Rex McElroy, a local man who had spent decades intimidating the town through a cycle of cattle rustling, arson, and assault. Despite being indicted for dozens of felonies over twenty years, McElroy consistently avoided conviction by threatening witnesses and exploiting legal loopholes, earning him a reputation as an "untouchable" outlaw.
The play received its world premiere as part of Sheffield Theatre's 202425 season. It began performances on 26 October at the Tanya Moiseiwitsch Playhouse and ran through 16 November.
The production transferred to the Southwark Playhouse Borough on 14 February 2025 and ran through 16 March. Holden reprised his performance from Sheffield.
The production subsequently returned to London at The Other Palace in late 2025. Performances began on 3 December 2025 and ran through 1 February 2026. The production was nominated for 6 Laurence Olivier Awards, including Best Play.
The production is scheduled to make its North American premiere Off-Broadway in New York City in the spring of 2026. The show is expected to begin performances on April 15 at the Lucille Lortel Theatre. Holden is expeted to reprise his performance.
