'Proof' Broadway review — Ayo Edebiri aces her Broadway debut in a revival that really adds up
Read our review of Proof on Broadway, the first revival of David Auburn's award-winning drama starring Ayo Edebiri, Don Cheadle, Kara Young, and Jin Ha.
Summary
- Proof follows a brilliant young woman dealing with the fallout of her genius yet mentally ill mathematician father's death
- The expertly realized revival is led by a shining Ayo Edebiri in her Broadway debut alongside excellent performances from Don Cheadle; Kara Young; and Jin Ha
- The show is recommended for fans of family dramas; math whizzes; and fans of Edebiri and Cheadle's screen work
Broadway just got smarter and deeper thanks to the return of David Auburn’s Proof, a complex, curvy, and thoroughly compelling play motored by a math-related mystery. We’ve been here before with this model of a well-made drama. Twenty-five years after it was honored with a Best Play Tony Award and a Pulitzer Prize, the taut two-act is still prime.
Auburn’s script raises a number of big things that matter — family, legacy, truth, and trust among them — and he deftly connects the dots between the themes while balancing tension and humor. He’s created four dynamic characters, and the cast, led by Ayo Edebiri and Don Cheadle, mine them for all their riches. Direction by Thomas Kail (Hamilton) shines with neon-bright sensitivity and a nimble pacing.
Considering the "mmms" from the audience after an early reveal and gasps following the game-changing three-word kicker in the first act, the play still packs surprises, despite its age and 2005 film adaptation. So, not one spoiler here.
The Chicago-set story revolves around Catherine (Edebiri), whose academic father, Robert (Cheadle), is a math whiz with mental illness. Has she inherited his genius? His cognitive disorder? Both? The discovery of a landmark proof about prime numbers, plus questions of its authorship, thicken the plot. It also amplifies concerns about Catherine.
Hal (Jin Ha), a brainy grad student who adores Robert, is one of the people in her orbit. And there’s Claire (Kara Young), Catherine’s overbearing sister who arrives from New York to manage her sib’s life. But that formula doesn’t check out for Catherine.
It’s altogether a pleasure to watch the play unfold, as it makes room for hope. Mathematicians seek to eliminate ambiguity, but life’s not like that. But there are zero debates about the cast stepping up. As Claire, Young, a four-time Tony nominee who’s won for Purlie Victorious and Purpose, hits all her notes as the acerbic and bossy but loving sister. Ha brings heaps of dorky appeal as Hal, who’s drawn to Catherine — and to a shot at advancing his career. Cheadle fills the addled dad with heart and raw vulnerability.
As Catherine, the showcase role that won Mary-Louise Parker a Tony in 2001, Edebiri aces a challenging stage assignment in a wry, lived-in, and persuasive performance. Catherine’s fears, desires, and frustrations all come through. Edebiri’s first Broadway star turn, like this revival, totally adds up.
Proof summary
David Auburn’s Proof — about genius, family, and identity — follows Catherine, the daughter of a brilliant but mentally ill mathematician who fears she’s inheriting his instability. A groundbreaking proof found in his office becomes a key source of conflict. The 2026 production at the Booth Theatre is the play’s first revival on Broadway, where it premiered in October 2000 following an Off-Broadway run earlier the same year.
In 2001, the play won three Tony Awards, including Best Play, and the Pulitzer Prize for Drama.
What to expect at Proof
The front porch of a multilevel home in the Windy City sets the scene for Auburn’s play. Between Teresa L. Williams’s set and lighting by Amanda Zieve, the house takes on a living quality, if not a state of mind. Sometimes, you can see through outside walls, as if in an X-ray. Or, a nod to theatrical designer Jo Mielziner's famous skeletal set for the original Broadway production of another celebrated family drama: Death of a Salesman.
Illuminated neon tubes along the roofline and elsewhere add eye-catching dimensions, and a final brilliant flash makes for a genius punctuation mark.
