The Man Who Knew Infinity

Overview

Early in Good Will Hunting, a maths professor (Stellan Skarsgård) tries to convince his therapist friend (Robin Williams) that a troubled janitor (Matt Damon) is actually a genius. To make his case, he mentions Srinivasa Ramanujan, a self-taught Indian prodigy who compiled thousands of theories at the beginning of the twentieth century. For many viewers, that's probably the only time they've heard his name — and they may not even remember it. Stepping through Ramanujan's story, The Man Who Knew Infinity endeavours to explain why he's held in such high esteem, and to bring the mathematical pioneer to wider attention.

Given that Ramanujan taught himself complex equations, earned the intrigue of academics on another continent and then proved his prowess to even the most skeptical of onlookers, he's certainly worthy of acclaim and recognition. As played by Dev Patel, his tale is filled with extraordinary achievements, spanning his childhood in Madras, his acceptance into Cambridge and his bond with his mentor, G.H. Hardy (Jeremy Irons). Sadly, it's also blighted by the prejudice of his peers, as well as numerous physical, emotional and spiritual struggles along the way.

There are only so many ways that a film can cycle through the life and times of people of note, with biopics often judged on three factors: how closely they stick to the usual formula, whether they're based around a convincing central portrayal, and if they manage to shine a spotlight on little-known facts or under-appreciated figures. While The Man Who Knew Infinity is guilty of the former in the most dutiful and conventional of ways, it's also boosted by Patel's measured yet moving performance, as well as the feature's earnest and noble attempt to pay tribute to Ramanujan.

Just as the groundbreaking maths wiz benefited from his working relationship with Hardy, however, Patel is at his best when Irons is by his side. The Slumdog Millionaire star might be working with his most significant role since his breakthrough appearance, but it's his veteran co-star who threatens to steal the show. As Irons exudes a mix of world-weariness, tenacity and elegance in every scene, Patel rises to match him. Of course, they're not merely playing their tweed-suited, teacher and student parts. Here, art is clearly imitating multiple layers of life.

Accordingly, as a showcase for its two key talents and as a celebration of its subject, The Man Who Knew Infinity never proves less than interesting — although writer-director Matt Brown doesn't always seem to realise that. In fact, in adapting the biographical book of the same name, the second-time filmmaker could've used a little of Ramanujan's dedication and enthusiasm, not to mention Patel's passion and Irons' charm. Preferring the slow, steady and sentimental approach, he makes all the obvious storytelling and stylistic choices, including keeping everything as polished as possible. Thankfully, the broader details win out over the overall method of delivery.
