Released in 2015, The Man Who Knew Infinity is a British biographical drama that brings to life the extraordinary yet tragically short journey of Indian mathematician Srinivasa Ramanujan. Directed by Juan Carlos Fresnadillo and adapted from Robert Kanigel’s 1991 biography, the film stars Dev Patel as Ramanujan and Jeremy Irons as his Cambridge mentor, G. H. Hardy.
At its heart, this film is not just about mathematics but about determination, cultural clashes, human connection, and the pursuit of truth in an era of prejudice. With a backdrop of World War I, audiences are shown how Ramanujan’s brilliance emerged against all odds, leaving a legacy that continues to inspire mathematicians and dreamers alike.

What Is The Man Who Knew Infinity About?
The story follows Ramanujan, a self-taught mathematical prodigy from Madras, India, who grew up in poverty but possessed an unparalleled gift for numbers and formulas. Despite lacking formal education, his insights led him to correspond with the esteemed Cambridge mathematician G. H. Hardy, who saw potential in him and invited him to England.
At Cambridge, Ramanujan battled:
-
Racial prejudice from a skeptical academic society.
-
Cultural displacement, struggling to adapt to life away from his homeland and his young wife Janaki.
-
Declining health, as his body weakened in the harsh British climate.
Yet, under Hardy’s mentorship, Ramanujan went on to produce groundbreaking work in number theory, infinite series, and continued fractions — contributions that remain essential to mathematics today.
