From Mubi:
Director Spike Jonze teams up with Arcade Fire to create a thirty-minute short film inspired by their critically acclaimed album, The Suburbs, and its themes of war and coming of age in suburbia. Co-written by Jonze & Arcade Fire’s Win Butler & Will Butler, this companion piece to the album follows the narrator, living in a suburban dystopia, trying to piece together fragmented memories from when he was a teenager, and his experiences with his friends as they grow apart. –SXSWAVAILABLE ON MUBI ON JUNE 27TH - Please SUBSCRIBE to *hipstereo.
