Kara Young will take on the role of Claire in the Broadway revival of Proof, stepping in after Samira Wiley withdrew from the production. According to the production, Wiley has stepped away because of a treatable medical condition that requires her complete focus. The change comes as the company finalizes preparations for performances at the Booth Theatre, where the revival is scheduled to begin a 16-week engagement on March 31, 2026, with an opening night set for April 16, 2026.
The cast assembled for this staging includes several high-profile names. Ayo Edebiri headlines as Catherine, with Don Cheadle portraying her late father, Robert, and Jin Ha appearing as a former graduate student. The arrival of Kara Young completes the quartet announced for the revival and positions the production to move forward without delay. Producers noted that the substitution was handled promptly so rehearsals and technical work could continue uninterrupted.
Who is Kara Young and why her casting matters
Kara Young arrives with strong Broadway credentials: she has been a recurring presence on New York stages and recently won consecutive Tony Awards for her performances in Purpose (2026) and Purlie Victorious (2026). Her casting as Claire — Catherine’s skeptical and protective sister — brings an actor familiar with both contemporary plays and the demands of Broadway-scale productions. Young’s recent Off-Broadway work and upcoming film projects also underscore a versatile career that spans stage and screen, which producers believe will serve the revival well.
Career context and recent projects
Beyond her Tony successes, Young’s résumé includes acclaimed roles in both new plays and revivals. She most recently appeared Off-Broadway in Rajiv Joseph’s Gruesome Playground Injuries and is attached to several film projects, including the adaptation of Alesha Harris’ Is God Is and Boots Riley’s I Love Boosters, the latter of which also features Don Cheadle. That cross-medium experience positions Young as an artist comfortable navigating emotionally complex material, a quality that aligns with the psychological weight of Proof.
Production details and creative team
The revival is directed by Tony winner Thomas Kail, who also serves as a producer alongside Mike Bosner. The production has drawn notable collaborators: President Barack Obama and Michelle Obama’s Higher Ground were recently announced as co-producers, adding institutional and cultural cachet to the staging. This is the first Broadway revival of David Auburn’s play, which won both the Pulitzer Prize and a Tony Award after its original production.
Venue, run length, and scheduling
Performances are slated to begin at the Booth Theatre on March 31, 2026, with the official opening night on April 16, 2026, and a planned run of 16 weeks. The producers have emphasized that despite the recent casting adjustment, the schedule remains intact. The Booth provides an intimate setting that supports the play’s focus on personal dynamics, mathematical obsession, and family legacy — all central themes the creative team is preparing to foreground.
About the play and what audiences can expect
Proof centers on Catherine, a brilliant but unsettled woman who sorts through the aftermath of her father’s death and the discovery of a notebook that may contain a groundbreaking mathematical proof. The drama interrogates authorship, genius, and the inheritance of mental illness: questions that challenge both the characters and the audience. In this revival, the interplay between Catherine, her sister Claire, and the men who shaped their lives anchors the narrative tension.
Members of the company have spoken about the live-theatre stakes of the piece and the desire to make the production accessible to diverse audiences. With a cast that mixes experienced stage performers and actors known from film and television, the revival looks to bridge theatrical intensity with broad appeal. Audiences can expect a production that highlights emotional clarity, precise character work, and the central mystery of the notebook at the heart of the story.
Final notes on the casting change
The producers and cast have expressed well wishes for Samira Wiley and emphasized that her departure is for health reasons described as a treatable medical condition. Meanwhile, Kara Young has officially joined the company and will perform the role of Claire when the revival reaches Broadway later this season. Ticketing and scheduling information is available through the theatre’s box office and the production’s official outlets.
