Review: Insight Theatre Company's Production of PROOF

In the academic world of mathematics "proofs" are a kind of intellectual currency. If published, they can launch a career. But, they're rare and precious items, essentially the product of sweat and genius; the very essence of math. David Auburn's play, Proof, examines this form of the word, but also visits upon many of the other meanings present as well. Filled with moments of drama, mystery and humor, Proof is a compelling tale that never bores, and Insight Theatre Company closes their season with a generally solid production of this clever and engaging work.

The play focuses on the character of Catherine, the daughter of the recently passed Robert, a college professor and mathematical genius whose career was curtailed by a prolonged and difficult battle with mental illness. Since his death, a former graduate student, Hal, has been going through his personal notebooks in an attempt to mine any pearls that may have been left behind. Though initially opposed to the idea, Catherine eventually warms to Hal, to the point where she gives him a key to a drawer hiding a proof relating to prime numbers. The stunning revelation of its authorship provokes the need to provide another kind of proof.

Colleen Caul effectively conveys Catherine's pain, depression, and determination, but the script also provides her with a veritable wealth of biting and caustic humor that goes untapped. John Contini is warm and appealing as Robert, and though he's seen as a ghost initially the story also flashes back to times when his character was splendidly lucid, as well as those when he was frustratingly compromised. Contini strikes a nice rapport with Caul, and Robert's infectious enthusiasm and passion for his life's work is evident throughout.

Erin Kelley plays Catherine's upwardly mobile sister, Claire, and she imbues the part with a genuine sense of caring, this in spite some of the more insensitive decisions her character makes. Matt Lindhart does capable work as Hal, who wants to believe in Catherine's abilities, but isn't convinced she has the inherent talent, regardless of her genetics.

Director Wayne Loui too often softens the edges of this sharply written work, and though that may make it more appealing emotionally, it blunts much of the Auburn's sarcastic wit in the process. Sarah Hoeynck's scenic design provides an appealing and inviting porch that's nicely lit by Sean Savoie. Tori Meyer's sound design makes good use of some moody cuts by jazz guitarist Bill Frisell, and Laura Hanson's costumes are good fits for the characters.

Insight Theatre Company's production of David Auburn's thought-provoking play Proof runs through October 10, 2010.
