About the Movie

The Man Who Knew Infinity is the true story of a friendship that forever changed mathematics. In 1913, Srinivasa Ramanujan (Dev Patel), a self-taught Indian mathematics genius, traveled to Trinity College, Cambridge, where over the course of five years, he forged a bond with his mentor, the brilliant and eccentric professor, G.H. Hardy (Jeremy Irons), while fighting against prejudice to reveal his mathematic genius to the world.

Top Critics' Reviews

Rotten: "The Man Who Knew Infinity," based on Kanigel's book, and directed by Matthew Brown, feels sluggish and stuck, and it hits an insoluble crux. – Anthony Lane, New Yorker, May 2, 2016

Fresh: "The Man Who Knew Infinity" shines a welcome light on a lesser-known figure in mathematics, but it isn't as illuminating as it could have been. – Rafer Guzman, Newsday, May 5, 2016

Fresh: Its craft is evident, its sincerity is admirable, and it's the kind of movie about which you can say, "There's not a hair out of place," and mean it. – Rex Reed, New York Observer, May 5, 2016

Fresh: The Man Who Knew Infinity stands on its own merit, thanks in great measure to Patel and Irons, who give us two engaging characters. – Miriam Di Nunzio, Chicago Sun-Times, May 6, 2016

Genius - highly recommended

Grea, truet story of the genius of Ramanujan, an uneducated Indian who gets invited to study at Cambridge - unheard of at any time. A great story of race, friendship, class - both Jeremy Irons and Dev Patel are superb and having visited Cambridge I was stunned that they actually were able to film there - never seen that before on film. A great, inspiring watch.


Great movie! This should be shown in all classrooms! THIS is greatness.

Moving story of friendship and mathematics

I was surprised by how much I loved this film about Ramanujan, a self-taught mathematician from Madras (now Chennai) who traveled to Cambridge, against seemingly insurmountable odds, to bring his incredible theories to the world. Jeremy Irons and Dev Patel are both fantastic and have terrific chemistry as the elder mentor and the young genius working together to share Ramanujan's discoveries and to have them published. However, if you think that a film about math is not for you, then I think you'd be wrong - because this is more than a film about a pivotal moment in the development of modern mathematics; it is chiefly a story about friendship and the mysteries of the intellect. I loved it and I think you will, too.
