TIFF Trailer: Math Drama 'X+Y' Starring Asa Butterfield, Sally Hawkins, Eddie Marsan And Rafe Spall

In 2007, director Morgan Matthews delivered his TV documentary "Beautiful Young Minds," which centered on a group of students participating in the International Mathematics Olympiad. Among the nods it received was a BAFTA TV nomination for Best Single Documentary, and now Matthews hopes the feature version of that story will get even more attention.

Asa Butterfield, Sally Hawkins, Rafe Spall and Eddie Marsan have joined forces for "X+Y." With a script by playwright James Graham, it tells the story of a borderline autistic kid whose love of numbers gets him on the British Math Team, where a trip to Taipei for the International Mathematics Olympiad brings the possibility of romance, and opens him up to a whole new life. Gotta say, we never felt this inspired while doing long division. Here’s the official synopsis:

For most of us, equations are just a means to an end. But for teenage math prodigy Nathan (Asa Butterfield), they’re a way of life. Diagnosed as being on the autism spectrum when he was a little boy, Nathan has always struggled to relate to people, even to his ever-loving and patient widowed mother, Julie (Sally Hawkins). Numbers (especially prime ones) are the only things that make sense to him. But when attentive teacher Mr. Humphreys (Rafe Spall) takes an interest in Nathan’s talents, doors begin to open.

Mr. Humphreys’s unorthodox teaching methods help land Nathan a spot on Great Britain’s team at the International Mathematics Olympiad, and the young math whiz finds himself travelling to a training camp in Taipei. Under the blustery guidance of squad leader Richard (Eddie Marsan), this group of socially awkward teens discovers that they might not be as weird as they thought themselves to be.

No release date yet for "X+Y," but it will have its World Premiere at the Toronto International Film Festival. Watch below.
