We aren’t given this glorious journey of a genius plucked from obscurity as much as we are the trials and tribulations of success. Brown’s film is all about the hardships thrust upon Ramanujan.

This is the very definition of the kind of movie people complain that “they” don’t make anymore: a modestly budgeted, character-driven drama for adults that doesn’t insult the viewer’s intelligence or lean on shock value.

The film is unashamedly middle-brow and sentimental but it tells such a good story that it is hard to resist.

Irons’s Hardy steals this film away from its ostensible hero, in part because pulling the shutters down makes him that much harder to know.

Well intentioned and played, this shows flashes of what could have been, but is ultimately let down by its timidity towards the maths, and fails to make the case for its own hero’s greatness.

Polite, earnest stuff, but it never quite adds up to much.

Highly engaging performances by Dev Patel in the lead role and Jeremy Irons as his curmudgeonly mentor gradually warm up the Cambridge story, but the Indian part feels perfunctory and unconvincing.

The arguments between Ramanujan and Hardy form easily the most absorbing aspect of The Man Who Knew Infinity, as their eloquent clash of wills is shown to be not just intellectual but ideological in nature.

In the end, The Man Who Knew Infinity never allows itself to transcend the sad irony of such biopics — that people known for thinking outside the box are always given film portraits that refuse to do so.

Irons is the gawky one. His Hardy is a socially inept bachelor who is ill-suited to the role of nurturing mentor and father figure.
