In the 1910s, Srinivasa Ramanujan is a man of boundless intelligence that even the abject poverty of his home in Madras, India, cannot crush. Eventually, his stellar intelligence in mathematics and his boundless confidence in both attract the attention of the noted British mathematics professor, G.H. Hardy, who invites him to further develop his computations at Trinity College at Cambridge. Forced to leave his young wife, Janaki, behind, Ramanujan finds himself in a land where both his largely intuitive mathematical theories and his cultural values run headlong into both the stringent academic requirements of his school and mentor and the prejudiced realities of a Britain heading into World War One. Facing this with a family back home determined to keep him from his wife and his own declining health, Ramanujan joins with Hardy in a mutual struggle that would define Ramanujan as one of India's greatest modern scholars who broke more than one barrier in his worlds.

A beautiful movie...
3 December 2018 | by Thanos_AlfieSee all my reviews

"The Man Who Knew Infinity" is a Biography - Drama movie in which we watch the true story of the Indian mathematician, Srinivasa Ramanujan. His story starts in Mandras a city in India where he makes his first steps in mathematics while searching for a job and goes until he arrives in Cambridge and starts working there. He faces many difficulties and makes some friendships such as with Professor G.H. Hardy who was also his mentor.

I liked this movie very much because it was a true story of a person who suffered a lot, facing any difficulties but eventually succeeded in his field. The direction which was made by Matt Brown was very good and I believe that the combination he made between the life of Srinivasa Ramanujan in India and what he sacrificed in order to go to England with the life that he was expecting before arriving in England and what he actually lived there was a very good idea. I enjoyed also the interpretation of Dev Patel who played as Srinivasa Ramanujan and for one more time, he was very good at it. Other interpretations that were very good and have to be mentioned are Jeremy Irons who played as Professor G.H. Hardy and Toby Jones who played as Littlewood.

To sum up, I believe that "The Man Who Knew Infinity" is a beautiful movie with a great plot based on an incredible person and pioneer in mathematics. I strongly recommend everyone to watch it because it's a life lesson from which everybody will gain something by watching it. Never stop dreaming and never stop fighting for something you love.
