By David Auburn
On the eve of her twenty-fifth birthday, Catherine, a troubled young woman, has spent years caring for her brilliant but unstable father, a famous mathematician. Now, following his death, she must deal with her own volatile emotions; the arrival of her estranged sister, Claire; and the attentions of Hal, a former student of her father’s who hopes to find valuable work in the 103 notebooks that her father left behind. Over the long weekend that follows, a burgeoning romance and the discovery of a mysterious notebook draw Catherine into the most difficult problem of all: How much of her father’s madness—or genius—will she inherit?

Notes from the Director
For those auditioning that have seen the 2005 film Proof, we will be directing this production in a way that may not be as serious as the movie in some places and leans into the sometimes inappropriately humorous moments that happen in families. We encourage you to read the sides and prepare for your audition without the movie’s portrayals in mind.
Please note that character ages are suggested based on the script but will not be a primary factor in casting decisions. Our focus will be on ensemble chemistry and performance. If the right dynamic is achieved, we are open to casting actors whose ages fall outside the suggested range.
Be prepared to embrace the late 1990s. Flannel shirts, chunky boots, great music!
Please be open and available to a wide range of publicity for the show.
Audition Sides
Characters
Catherine
Age: late 20s
Background: Catherine has spent several years caring for her mentally ill father, Robert, a once-renowned mathematician. She is brilliant in her own right, having inherited her father’s mathematical talent, but she struggles with self-doubt and fears she may also have inherited his mental illness. Catherine seeks validation and trust—not just from others but from herself as well as credibility in a male-dominated field.
Robert
Age: Late 50s to early 60s
Background: Robert’s mental health has deteriorated over the years due to an unspecified illness (likely schizophrenia or bipolar disorder). The challenge to this character is in flashback he is played erratic and obsessive, but in other scenes he is charismatic, intense, and lucid.
Hal (Harold Dobbs)
Age: 28–30
Background: Hal is a young mathematician who studied under Robert and is now going through his notebooks, hoping to find valuable work. He respects Robert and is intrigued by Catherine’s mind and story. Earnest, well-meaning, and slightly awkward. He wants to do right by Catherine but is sometimes blind to how his actions can come across as patronizing or dismissive.
Claire
Age: Early 30s
Background: Though not mathematically inclined, she often takes a caretaking and managerial role, sometimes to Catherine’s resentment. Responsible, controlling, well-intentioned but emotionally distant. She struggles to connect with Catherine and often underestimates her.
