Formerly titled "X+Y" when it debuted at the 2014 Toronto International Film Festival, Morgan Matthews' coming-of-age drama finally hit theaters this summer under the title "A Brilliant Young Mind." Starring Asa Butterfield, Sally Hawkins and Rafe Spall, the film is a narrative take on Matthews' 2007 documentary "Beautiful Young Minds." Both films earned acclaim for their authentic depictions of what it's like living with autism.
Butterfield stars as Nathan, an autistic teenage math prodigy being mentored by his unconventional and anarchic teacher, Mr. Humphreys (Spall). When it becomes clear that his talents are enough to earn him a place on the British team competing at the highly-revered International Mathematics Olympiad, Nathan heads to Taiwan for an unforgettable, life-affirming journey.
In an exclusive behind-the-scenes clip above, Matthews sits down to discuss what it was he looked for while casting his eponymous young mind and why Butterfield fit the bill. "A Brilliant Young Mind" hits DVD and Digital HD tomorrow, January 26.
