kara young leaving proof broadway takes a sharper turn on June 30, when Adrienne Warren enters the Booth Theatre production as Claire. Young will leave the role on June 28, two days earlier, after booking her previously announced commitment to The Whoopi Monologues at Lincoln Center Theater.
Booth Theatre cast shift
June 30 gives Proof a clean handoff. Warren, a 2021 Tony Award winner for Best Actress in a Musical for Tina: The Tina Turner Musical, arrives in a Broadway revival that opened at the Booth Theatre on April 16 and already has Ayo Edebiri, Don Cheadle, and Jin Ha in the ensemble.
June 28 closes out Young’s run as Claire, and that timing leaves the production with only a brief gap before Warren steps in. For a currently running revival, that kind of change is less about promotion than continuity: the role stays filled, but the performance identity shifts with one of Broadway’s more recognizable musical-theater names moving into the part.
A Tony winner replaces a Tony winner
2021 is the year that matters most on Warren’s resume here. She won her Tony for Tina: The Tina Turner Musical, appeared most recently onstage in New York City Center Encores! The Wild Party, and played Cathy in the Broadway revival of The Last Five Years last year, giving Proof another performer with current stage time and a Broadway track record.
Young’s departure carries its own weight because she is a two-time Tony winner. That makes this a cast change with more than routine turnover attached to it; the production is swapping one award-winning performer for another while the show is still in run mode at the Booth.
Proof keeps its awards profile
David Auburn’s Proof comes with its own prestige. The play is Tony- and Pulitzer-winning material, and Thomas Kail’s production adds original music by Kris Bowers, so the revival is already built around recognizably high-end names before Warren steps in.
For ticket buyers and theatergoers, the practical read is simple: the Claire they see after June 30 will be Warren, not Young, and the production is signaling that it plans to keep the Broadway run moving without losing tempo. That is the real story here — not a pause, but a cast replacement inside a live Broadway run, with the handoff happening in forty-eight hours.
