The Carrier stars Rita Wilson as a woman who becomes both messenger and spectator in the painful unraveling of a family secret. Barr says his background in naturalistic filmmaking helped reinforce the fluid, handheld camera style he used to capture Wilson’s emotionally charged confrontations. Operator John Barr, who began as a gaffer in Maine before going to L.A. in the late 1990s for a temporary stint on a television show, says he had no intention of staying. But a childhood passion for movies and lighting kept him tethered to Hollywood. He joined the Guild in 2003, working mainly in commercials, and then later with Adam Kimmel, ASC on Capote, and Salvatore Totino, ASC on Frost/Nixon.
