Ramanujan was well known to many mathematicians in the Madras area and he was finally able to obtain employment as clerk in 1912 at the Madras Port Trust. In fact, the Chief Accountant for the Madras Port Trust was a trained mathematician and he clearly recognized Ramanujan's abilities. Eventually Ramanujan's work came to the attention of G.H. Hardy, a resident at Trinity College, Cambridge when he received a letter from him in early 1913. Ramanujan had contacted various other professors in England without much success. However Hardy was most interested. Ramanujan's letter contained a long list of unproven theorems and Hardy wanted some proofs. Ramanujan desperately wanted to travel to England but he required a scholarship to do so. With Hardy's help he was able to obtain a scholarship for two years from the University of Madras and travelled to England from India in 1914.

The film portrays Hardy's efforts along with his colleague John Edensor Littlewood (who is played by Toby James) to give Ramanujan the mathematical training he needs. Hardy is seen relentlessly insisting that Ramanujan must provide proofs of his theorems. Meanwhile, Ramanujan seeming to sense he is running out of time, is determined to see his work published.
In fact as World War I dragged on and the vegetables Ramanujan often ate became scarce his health began to suffer. Ramanujan had previously been ill in India and in 1917 he became seriously ill in England. In the movie, he is seen frequently visiting the medical tents set up on campus for the injured soldiers sent back from the front in Europe. The film suggests that Ramanujan was thought to have tuberculosis, although the diagnosis of exactly what was wrong with him was never fully determined.
The Man Who Knew Infinity captures the historical period well, providing viewers with a sense of the obstacles Ramanujan faced upon arriving at Trinity, and the struggles his fellow mathematicians had in understanding and accepting him. Two mathematicians, Ken Ono and Manjul Bhargava were involved in the making of the film to ensure the mathematics was accurately portrayed. The movie was ten years in the making and premiered at the 2015 Toronto Film Festival. Well worth the wait and definitely worth viewing.
This short biography of Srinivasa Aiyangar Ramanujan from the MacTutor History of Mathematics website is worth reading.
As shown in the movie and stated near the end, Ramanujan left a number of books and manuscripts containing his ideas and theorems, all of which have since been proven. Work on his ideas continues to this day as this article from Science Daily explains. This more recent article from + plus Magazine: Living Mathematics 2015 is also quite interesting.
