Tamil Srinivasa Ramanujan is toiling away as a clerk in Madras, a maths prodigy who is entirely self-taught and with little future in his home country. His work leads Professor GH Hardy to bring him to Cambridge and a difficult career ensues throughout WW1. Adapted by writer/director Matthew Brown from the book by Robert Kanigel, this biographical drama is puzzling and touching in equal parts: the beauty of mathematics is difficult to convey to a dimwit like myself but the relationships and overt racism on campus bring out the best in Dev Patel’s acting skills. The essence of his character is religious faith – he eventually confesses to the gruff and irascible atheist Hardy (Jeremy Irons) that he believes his God is speaking to him in his sleep. Hardy’s inspiration is less theological and his insistence on proofs leads Ramanujan to a period of self-doubt, depression and serious illness. Hardy becomes his friend very late in the day, following racist attacks, vicious rivalries within the University and a declining marriage: back home in India, Ramanujan’s mother has been hiding the letters his illiterate wife was writing to him and his wife doesn’t know and ultimately writes to inform him she is leaving him. This is a beautifully handled drama about a little known man whose work during the last year of his life has been used to understand black holes. What was that about infinity and beyond?! Ah, sweet mystery of life. Gimme dat ol time religion.
