The most persuasive aspect of the film is the way a friendship slowly grows between Ramanujan and Hardy. Showing a more subtle side to his talent than his over-enthusiastic comic turns in the Exotic Marigold Hotel films, Dev Patel plays Ramanujan with the giddy excitement of a passionate, impetuous enthusiast exasperated that others cannot keep pace with his buzzing mind. Infinity captures many aspects of the Ramanujan story from the man of humble origins struggling to gain acceptance for his brilliant mind, to a weary exile in a far, foreign land who is separated from his wife. The outbreak of the First World War stiffens the resistance to the presence of a foreigner and Srinivasa is worn down by the violence and humiliations routinely heaped upon him. Hardy wants proof and rigour from work that just seems to come naturally to Srinivasa. Treated as an exotic curiosity, Srinivasa struggles. Hardy (Irons) who invites him to come and study in England. Employed in Madras as a clerk to Sir Francis Spring (Stephen Fry), Srinivasa is encouraged to send samples of his theories to Cambridge academic G.H.
Ramanujan (Dev Patel) may have had no formal training but he is an instinctive mathematical genius. It seems a little too Merchant Ivory, a little Laura Ashley.
Initially, The Man Who Knew Infinity seems stifled by its own sense of craft, including cinematography by Larry Smith that bathes the screen in a golden glow and serves up beautiful images of India. It tells such a good story that it is hard to resist The old-fashioned virtues of a well told tale and a particularly fine performance from Jeremy Irons should endear the film to that supposedly under-served older demographic who like to turn out for a weekday matinee.
A well-heeled, sincere production following the memories of Ramanujan’s English mentor and friend, the film is unashamedly middle-brow and sentimental but it tells such a good story that it is hard to resist. The true story of groundbreaking Indian mathematician Srinivasa Ramanujan, the “Prince Of Intuition” forms the basis of an inspirational tearjerker in The Man Who Knew Infinity.
