James Sizemore is a composer, arranger, and producer with notable credits in film and television. James’ music ranges from the additional music in the family film A Dog’s Purpose, to adding string arrangements to M Night Shamylan’s dark film Split.

James composed additional music and arranged and produced the score for the award winning film Spotlight. Previously James spent 3 years working with director Peter Jackson and composer Howard Shore, orchestrating and arranging the music for The Hobbit Trilogy.

With a versatile background in many musical styles, he has ranged from the big broadway musical numbers written for the recent OJ:The Musical  to the ambient soundscapes heard in David Cronenberg’s films Maps to the Stars and Cosmopolis. His versatility can also be heard in Jon Stewart’s film Rosewater, where ethnic Persian soloists intermingle with hip-hop and rock influences.
