BFI and BBC Films, 2014


The debut feature film from director Morgan Matthews, inspired by the documentary Beautiful Young Minds, X+Y focuses on an English teenage maths prodigy named Nathan (Asa Butterfield) who has difficulty understanding people, but finds comfort in numbers.

When he is chosen to represent the United Kingdom at the International Mathematical Olympiad, Nathan’s mathematical brain collides with a new and baffling equation for the first time: love.

Competitive maths + teenage romance = an intelligent and engaging entertainment
