There’s plenty of accolades given to actors and directors, and even the visual effects wizards but you could argue there’s not enough credit given to the geniuses behind the soundscapes of movies. Making Waves: The Art of Cinematic Sound has seen fit to put that right, looking at the world of sound design and focusing on three maestros who have all at times been involved in the Star Wars saga.

Eventually “Making Waves” settles in and focuses on three iconic and groundbreaking sound designers, and details their careers and their innovations with in-depth interviews and examples. Walter Murch (“Apocalypse Now”), Ben Burtt (“Star Wars”) and Gary Rydstrom (“Jurassic Park”) soak up quite a bit of credit in the historical section of the documentary, but Costin makes a fine case for their accolades.

“Making Waves” treats Murch, Burtt and Rydstrom — all of whom contribute their expertise and anecdotes to the production — like rebel rock stars, which they are. They’re just really nerdy, laid-back rebel rock stars, who really love making movies. You kinda gotta love them.
