Their rare and at times fraught collaboration makes for an entertaining film. This is in spite its sprinkling in bits of math throughout, which some viewers might find daunting. For example, upon hearing about a taxi's number 1729, Ramanujan pointed out that that it's the smallest number expressible as the sum of two cubes in two different ways (1 cubed plus 12 cubed and 6 cubed plus 10 cubed).

Ten cubed plus nine cubed.
In the article it’s 9 cubed plus 10 cubed, not 6 cubed.
