Thursday evening the Brattle will feature “the loudest sound”, an independent film by Brookline resident Director Jason Miller. The film depicts a young Boston couple and the breaking of their three-year bond by addiction and betrayal through the visual interchange between color and black and white. Miller says the inspiration behind the film is a mix of personal experience and a desire to write film stories that depict the truths and challenges of interpersonal relationships. “The relationship depicted with Michael and Alice,” the film’s focal characters, “has shades of codependency that affects many couples,” Miller says. Miller adds that “As a film, a lot of inspiration came from the great American movies of the 1970's” which were, “Films that dealt with big ideas, and never shied away from open and honest portrayals of [the] characters.” The choice to move visually between color and black and white Miller describes as representing the “motivations and the ever-changing dynamics of the relationship.” Although the couple is young, Miller believes the trials Michael and Alice face are more universal, but being inexperienced certainly doesn’t make things easier for them.
