Critics Consensus

The Man Who Knew Infinity might be a tad too conventional to truly do its subject justice, but Dev Patel and Jeremy Irons elevate the end result beyond mere biopic formula.

The Man Who Knew Infinity is moving, but not as compelling as the real life story of the genius it celebrates. The definitive film on Ramanujan remains to be made...

2.5/5

Conventional biopic The Man Who Knew Infinity focuses less on its protagonist, the Indian mathematician S. Ramanujan, than on the Brits who worked with him.

2/4

When one of the most enlightening moments of a film comes during the postscript (black holes!), you know there's a problem - one that has nothing to do with math.

It feels too often like an exam for which we haven't studied.

A bit by the numbers but nonetheless deserves a place on the shelf between A Beautiful Mind and The Imitation Game .

Patel and Irons deliver amazing work, but somehow I expected more.

An underrated film, as my opinion, a must watch film. This biopic beautifully captured the life of Sir Srinivasa Ramanujan.

The script and the filming are every bit as good as chariots of of a fire, except that all the characters are likable. The movie leave you with a feeling that you wish you had friends like that.

I doubt the truth of this (or most such 'high society' stories for that matter) is anywhere near this innocent, but a reasonably touching and enjoyable meditation nevertheless.

As mentioned the cast is fantastic, icons of the British theatre. One detail I thought important and considering mathematicians as scientists, why was Srinivasa allowed to mingle with the public as his tuberculosis worsened. My mother contracted tb back in 1930s in Butte, MT and spent a year in a sanatorium. Didn't they hospitalize such cases back at the time the storytook place?
