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.

Did You Know?

When Ramanujan arrives at Trinity College, Littlewood points to a tree and claims that is the tree where Newton got hit in the head by an apple and "invented"/discovered the theory of gravity. It is generally believed that Newton achieved the key insights to develop the Theory of Gravity while Cambridge was closed due to the Great Plague (August of 1665 through March of 1667); so even if the story of the apple were true, it would not have occurred at Trinity College.

Additionally, the tree is called a sapling -- which it clearly is not. Further, if the tree had been there at the time of Newton, then could not be a sapling at the time this event occurred. See more »


S. Ramanujan: There are patterns in everything. The color in light, the reflections in water... in math, these patterns reveal themselves in the most incredible form. It's quite beautiful.

Outstanding script and acting
5 April 2016 | by alpeshpatel-77898See all my reviews

An important film; cleverly mixing a love story with the equally deep themes of moral obligations on privilege to raise those without. At first I was concerned I would not be able to disassociate Dev Patel from the role on Marigold Hotel, but after a few lines which sounded too contemporary, he improved significantly.

Jeremy Irons was captivating and the other roles adequately developed. The direction, pace, setting, wardrobe, story, score -all hold the attention.

When I watched it, at the end, the audience applauded. In fact at the end of it, one wishes it could last longer - craving more.
