New York-based actor and writer Sean Gullette first gained international recognition as Maximillian Cohen, the troubled mathematics genius in Darren Aronofsky's film Pi. Gullette studied literature at Harvard, graduating Magna Cum Laude in 1991, as well as receiving acting training in New York and London. Pi was Gullette's first feature; he previously appeared in several short subjects, including Aronofsky's thesis film Supermarket Sweep and Nicole Zaray's Joe's Day, in which he played opposite Deborah Harry. Gullette's background in theater includes leading roles in Ibsen's Peer Gynt, Sartre's No Exit, and Sam Shepard's Curse of the Starving Class, the last of which Gullette also directed. In addition to starring in Pi, Gullette co-wrote the film's original story and helped design its promotional website.
