Maximillian "Max" Cohen (Sean Gullette) is the narrator and math addict who theorizes about numbers. He interacts with his mentor Sol Robeson (Mark Margolis) while suffering from a lot of disorders such as headaches, paranoia, hallucinations, and social anxiety disorder. Lenny Meyer (Ben Shenkman) strikes a conversation with Max.
Its screenplay was wonderful with the quotes from Max – “There are patterns everywhere in nature.” “I'm trying to understand our world. I don't deal with petty materialists like you.” Some of the theories were enthralling and logical. The score was upbeat much like the rest of the directors films and acting was sincere. Topics relating to mathematics, religion, fixations, illusions, being at peace and sense of reality were portrayed in Pi, a good thriller that is rare to view these days.
