Catherine must establish the authorship of a mathematical proof found in the office of her brilliant but troubled father. The return of her estranged sister and a burgeoning romance with her father's former student complicate her pursuit of truth in "Proof" by David Auburn, a compelling Tony Award-winning play directed by Christian Parker. "Proof"runs at Merrimack Repertory Theatre (MRT) from March 21-April 14. Tickets begin at just $20 and are on sale now thru MRT.org or by calling 978-654-4678.

Director Christian Parker, a native of Andover, MA, and now Associate Artistic Director of the highly-regarded Atlantic Theatre Company in New York City commented on presenting "Proof" at MRT. "I have a long history with 'Proof'. David Auburn has been a friend of mine for years, and I was among the first people to read the play when he wrote it. I advocated for its production at Manhattan Theatre Club and had the great fortune to serve as the dramaturge on the original production when MTC did it and moved it to Broadway. I always knew that the play would have really wide appeal. It's simultaneously a throwback to the great well-made American family plays of the mid-20th century and a really contemporary look at what we inherit from our parents and how we embrace or neglect the essential elements of who we are. The play is smart, funny, and presents a fascinating puzzle at its core. I am so thrilled to have the opportunity to return to this play with a killer cast at MRT's beautifully renovated theatre. It's the first time I've worked professionally as a director so close to where I grew up in Andover, so it's especially exciting to be doing so with a play I know so well, and love so much."

"Proof" will feature Keira Keeley as Catherine, Michael Pemberton as Robert, Colby Chambers as Hal, and Megan Byrne as Claire. Megan Byrne returns to the MRT stage (The Voice of the Turtle), while Keira Keely, Michael Pemberton, Colby Chambers, and director Christian Parker are all making their MRT debut. The creative team for "Proof" consists of Lauren Helpern (Set Design), Bobby Tilley (Costumer Designer), Josh Bradford (Lighting Designer), and Jason Weber (Sound Designer).
