The Man Who Knew Infinity (PG) This elegant film about Indian mathematical genius Srinivasa Ramanujan took 10 years to bring to the screen. The main story is about Ramanujan’s five years at the University of Cambridge to work on and publish his groundbreaking theories. Ramanujan is played by the earnest, endearing Dev Patel ( Slumdog Millionaire) and his mathematics professor, GH Hardy, is superbly inhabited by Jeremy Irons, in one of his best performances. The chemistry between the two is thrilling in a fractured way. The script is intelligent and sharp, full of seriousness and humour. I can’t say anything informed about the maths but the fact two high-profile mathematicians, Manjul Bhargava and Ken Ono, are on board as associate producers means it probably adds up.
