You don’t person to travel equipped pinch a knowledge of super-advanced mathematics, aliases moreover cognize what two-plus-two equals, to grasp, from nan very commencement of Thomas Kail’s caller revival of David Auburn’s Proof, that Ayo Edebiri, truthful bully connected TV’s edifice play (or comedy?) The Bear, and nan Oscar-winning Don Cheadle are astir to make thing typical of their Broadway debuts.
With a rapport that conveys nan heavy emotion and prickly exasperation of nan begetter and girl they portray, Edebiri and Cheadle instantly liking a declare to nan shape of Broadway’s Booth Theatre – wherever nan play opens coming – a declare they’ll stock soon capable pinch 2 arsenic good actors (Jin Ha and nan ever astonishing Kara Young), each to bring life to Auburn’s bonzer activity that primitively debuted connected Broadway successful 2000 and went connected to triumph some a Tony Award and a Pulitzer Prize.
With 2 of nan astir arresting first-act surprises this broadside of Becky Shaw‘s kinda-sorta pseudo-brother-sister kiss, Proof accomplishes nan improbable though intelligibly not impossible: It makes mathematic equations and nan eccentric geniuses who dream them up look nan worldly of enigma novels and family drama. Director Kail (Hamilton) skillfully guides and paces his fantabulous formed done immoderate heady worldly pinch large affectional stakes.
Edebiri plays Catherine, a 25-year-old assemblage dropout who we first brushwood having a late-night back-porch chat pinch her dad, nan superb mathematician Robert (Cheadle). The conversation, by turns comfortable and touchy, is acquainted enough. Dad wants to cognize why his once-promising scholar-daughter is wasting her life distant astatine nan family home, sleeping late, moping, squandering her talent and abandoning nan dreams they some erstwhile dreamed.
Within minutes we understand what’s going on: Catherine, it seems, is paralyzed pinch nan fearfulness that she, for illustration her celebrated and once-prolific father, will descend from brilliant to madness (“bughouse” is nan catch-all building used, apparently, and not wholly convincingly, to debar getting into technical-medical weeds). The very speech that opens nan play could beryllium much denotation than sign: Robert, we quickly learn, has been dormant for days. This chat is solely successful nan mind of Catherine.
Catherine’s evident stasis is interrupted by nan arrivals – intrusions, much aptly – of 2 people: Her loving and worrying if controlling sister Claire (Young), visiting Chicago from New York and wished to return complete not only nan ceremonial arrangements but her younger sister’s future. Like Blanche DuBois, Catherine “stayed and struggled” (to quote Tennessee Williams) while Claire, for illustration Stella, went disconnected for greener pastures. Resentments return correct alongside Claire.
Also new(ish) to nan homestead is Hal (Ha), a favourite student of Robert’s who implores Catherine to assistance him continued entree to nan master’s papers for nan liking of posterity and successful nan sanction of discovery. What if Robert had, contempt each outward appearances, been mentally and mathematically progressive these past years, processing nan intricate and groundbreaking “proofs” that were nan ground of his early career?
After a boisterous ceremonial wake, Catherine and Hal springiness successful to their communal attraction and, convinced of his bully intentions, Catherine agrees to assistance Hal afloat entree to dad’s stashed-away work.
Proof does not travel nan dramaturgical equation you mightiness person worked retired for yourself. We can’t beryllium judge of nan young man’s motives, astatine slightest initially, and we don’t person overmuch logic to expect a needle of brilliant successful nan haystack of Robert’s “all activity and nary play makes Jack a dull boy” gibberish.
But we’d beryllium wrong. Hal does so find what conscionable mightiness beryllium an historical and revelatory activity of brilliance, stunning some himself and Claire. Catherine? Not truthful much. She knew it was location each along, moreover provided Hal pinch nan cardinal to its locked-away place.
To explicate Catherine’s first reluctance to stock her dad’s mathematical masterpiece pinch Hal (and nan remainder of academia) would beryllium to spoil acold excessively overmuch of Proof‘s first-act leap and 2nd enactment plot. Enough to opportunity that nan revelation, erstwhile it comes, destabilizes nan cautiously constructed worlds of each concerned.
The action – and these incisive conversations surely feel progressive – unfolds successful beforehand of Teresa L. Williams’ lovely, elemental house-frame set, lit by ever-shifting neon-style colors that propose shifts successful some clip and temper (Amanda Zieve is nan lighting designer). Dede Ayite’s costume creation nails each character, from Catherine’s slouchy, depressing sweats-and-flannels to Claire’s chic, New York casual-glam.
The formed assembled present is easy 1 of nan champion connected Broadway correct now. Edebiri was, frankly, nan chaotic card, an intriguing spot of casting that nevertheless had folks wondering whether her thoughtful, interior-facing style that is truthful effective connected tv would construe onto a Broadway stage. It does. Her Catherine is little defined by nan quirky, appealing eccentricities of Mary-Louise Parker’s capacity successful nan original 2000 Broadway staging, but is girded by a definite angry resignation, fearful of what life mightiness person successful store, furious too, yet seething pinch a will to defy it all.
If Edebiri is nan revelation, her co-stars are pinch her each measurement of nan way. Even though he, too, is making his Broadway debut, Cheadle arrives pinch nan expectations that travel a long, stellar movie career, and he does not disappoint. Whether appearing successful his daughter’s unreliable imagination aliases successful what we presume are reality-accurate flashbacks, Cheadle’s Robert encompasses some nan play’s grounding unit and its suggestions of instability. He is nan story’s reliable halfway of gravity, isolated from erstwhile he isn’t.
Ha, awesome successful a mini domiciled successful Lincoln Center’s 2024 staging of Sondheim’s A Little Night Music, is moreover much truthful here. His Hal is adjacent parts romantic, pragmatist and savior (though who, exactly, he’s trying to prevention – Robert, Catherine aliases himself – isn’t clear until nan infinitesimal it should be).
And erstwhile again, Young, arsenic nan chopper sister, proves her inestimable worth to nan Broadway stage. Her fierce committedness to each domiciled she takes – comic, dramatic, some astatine erstwhile – is thrilling to watch. Stepping into nan domiciled arsenic a last-minute replacement for an ailing Samira Wiley past month, Young already holds a Tony Award grounds pinch 4 consecutive nominations for her first 4 Broadway performances from 2022 done 2025 (she won successful 2024 for Purlie Victorious and 2025 for Purpose, nan first Black character to return nan trophy 2 years successful a row.) The Broadway play still has overmuch to unfold, but nary 1 should beryllium amazed if Young adds to her way grounds travel information time.
