"The Man who knew Infinity" is a 2015 charming biography of one of the major figures in pure math around the turn of the 20th Century in Cambridge. The focus of the story is on the relationship between the gifted student (Dev Patel) and the experienced professor (Jeremy Irons), and there are the obligatory references to Patel's life in India and problems with an Indian trying to integrate at one of the premier English universities.

The film is slow paced and has none of the interest or drama of similar biographies ("Dangerous Mind", "Brief History"). The performances are uniformly good even from the small cameos (Stephen Fry, Kevin McNally). On balance, though, there is little to recommend unless you enjoy these kinds of biographies.
