Look Back on the Original Broadway Production of Proof Starring Mary-Louise Parker

David Auburn’s Tony- and Pulitzer-winning play Proof finally makes its return to Broadway after over two decades.

This current revival, which began previews in late March and opens at the Booth Theatre on April 16, stars Emmy Award winner Ayo Edibiri (The Bear) and Golden Globe winner Don Cheadle (Hotel Rwanda), who are both making their Broadway performance debuts in their respective roles.

Edebiri stars as Catherine, the brilliant yet anguished daughter of renowned, late mathematician Robert, played by Cheadle. Proof follows Catherine’s coming to terms with the loss of her father and the mental battle he faced shortly before passing. On the eve of her 25th birthday, she must balance a potential romance blooming between herself and her father’s former pupil, Hal (Jin Ha), the arrival of her estranged sister Claire (Kara Young,) and her family legacy following the discovery of a perplexing mathematical proof in one of Robert’s old notebooks.

Proof first opened Off-Broadway at the Manhattan Theatre Club on May 23, 2000. The production quickly moved to Broadway's Walter Kerr Theatre, opening on October 24, 2000, and running 917 performances until January 5, 2003. That meant Proof is one of the longest-running Broadway plays of the 21st century (number one is currently held by Harry Potter and the Cursed Child.)

Proof originally starred Golden Globe winner Mary-Louise Parker as Catherine, Obie Award winner Larry Bryggman as Robert, Golden Globe nominee Ben Shenkman as Hal, and Tony nominee Johanna Day as Claire. Notable cast replacements include Neil Patrick Harris, Jennifer Jason Leigh, Anne Heche, and Josh Hamilton.

In 2001, Proof went home with three Tony Awards: Best Play, Best Direction of a Play for Daniel Sullivan, and Best Actress in a Play for Parker. The play also took home two Drama Desk Awards (Outstanding Actress in a Play for Parker and Outstanding Play for Auburn,) the Drama League Award for Distinguished Production of a Play, and the 2001 Pulitzer Prize for Drama.

Internationally, Proof premiered on the West End in 2002 and in Australia at the Sydney Opera House in 2003. A film adaptation, directed by John Madden and adapted by Rebecca Miller, was released in 2005, with slight adjustments that included the addition of several minor characters outside of the typical four-person cast. The film version starred Gwyneth Paltrow as Catherine, Anthony Hopkins as Robert, Jake Gyllenhaal as Hal, and Hope Davis as Claire. Paltrow received a Golden Globe nomination for her role.

“I wanted to wait for the right cast, the right creative team,” Auburn shared in a video interview with Playbill regarding the 2026 revival of Proof. “When we saw the play read for the first time with this company, which was about nine months ago, maybe a year ago, it was immediately clear. This is what we had been waiting for, and this is the group that should revive it.”

Edibiri shared that having a Black family as the focal point of this current production resonates in different ways than the original. “Sometimes you talk or you don’t talk about certain things, when people do well and when people are not doing well, when they’re ill, it’s been fun to continue having those conversations.”
