“Hugo” and “Boardwalk Empire” took top honors at Saturday’s 48th annual Cinema Audio Society Awards, held at the Biltmore Hotel in Los Angeles.“Hugo,” Martin Scorsese’s cinematic love letter to film history, was honored for outstanding achievement in sound mixing for a motion picture, while “Boardwalk Empire,” which Scorsese exec produces, won sound mixing for television. But Scorsese wasn’t the only marquee name the evening’s two big winners shared. Re-recording mixer Tom Fleischman worked on both projects’ teams, giving him the evening’s only double win in film and TV. Fleischman has a previous film win for “The Aviator” and also won for “Boardwalk” last year. Fleischman shared the win with production mixer John Midgley and scoring mixer Simon Rhodes for “Hugo” and with production sound mixer Franklin D. Stettner for “Boardwalk.” The miniseries “Too Big to Fail” and reality series “Deadliest Catch: New Blood” earned TV honors, as well. Penelope Cruz presented the honorary CAS Filmmaker Award to director Rob Marshall. Walter Murch and Thomas Newman gave the CAS Career Achievement Award to Scott Millan.
