Broadway’s Proof will soon look different onstage, with Tony Award winner Adrienne Warren set to join the revival as Kara Young prepares to leave the production.

Producers announced that Warren, known for Tina: The Tina Turner Musical, will take over the role of Claire next month. Young will depart on Sunday, June 28, according to the announcement, as she moves on to a previously disclosed commitment to Lincoln Center Theater’s The Whoopi Monologues. The shift gives the revival a new marquee name while preserving momentum during its run.

A high-profile Broadway revival now faces a pivotal handoff, swapping one acclaimed performer for another without slowing the production’s pace.

The casting change lands at a moment when Broadway productions increasingly depend on recognizable talent to sustain attention well beyond opening night. Warren brings major stage credentials and strong audience recognition, and her arrival signals that the producers want Proof to remain firmly in the conversation. Reports indicate the transition has been planned around Young’s already announced schedule, not any sudden disruption inside the production.

Key Facts

  • Adrienne Warren will join Broadway’s Proof next month as Claire.
  • Kara Young leaves the production on Sunday, June 28.
  • Young exits due to a previously announced commitment to Lincoln Center Theater’s The Whoopi Monologues.
  • Producers announced the cast change today.

For theater fans, the handover pairs two performers with strong reputations but very different recent trajectories. Young exits to take on another prominent stage project, while Warren enters a revival of David Auburn’s drama carrying the weight of a Tony-winning profile. That kind of exchange does more than refresh a cast list. It can reshape how audiences, critics, and ticket buyers read a production in its next phase.

What happens next matters for both the show and the wider Broadway season. Proof now has a fresh reason to draw attention, and Warren’s first performances will likely become a focal point for fans tracking the revival’s staying power. At the same time, Young’s move to The Whoopi Monologues adds another thread to a competitive theater calendar, where casting changes often signal where the industry’s energy is heading next.
