The Man Who Knew Infinity

The Man Who Knew Infinity (2016) is a British-American biographical drama you can watch online on iFILM. Director Matt Brown traces how Srinivasa Ramanujan — a self-taught mathematician from Madras with no university degree — arrived at Cambridge during World War I and upended everything the faculty thought it knew about numbers.

Dev Patel plays Ramanujan opposite Jeremy Irons as the rigid, deeply skeptical professor G. H. Hardy. Hardy sees theorems that should take decades to derive, and Ramanujan cannot explain where they come from — he just knows. Their collaboration is a collision of two worldviews: one shaped by rigorous proof, the other by pure intuition.

Based on Robert Kanigel's biography, the film strips away the "tortured genius" cliché and focuses on the practical cost of being extraordinary — poverty, illness, cultural displacement. Stream The Man Who Knew Infinity (2016) online on iFILM.
