When Alex Garland's latest film, Civil War, was released earlier this year, there was a lot of talk about the sound design of the film and its ultra-realistic take on the sound of battle. I was invited by the sound team to come to Pinewood Studios, near London, to hear the film in the room it was mixed in. We talk about the decision process they went through to land on the innovative mix of the film. Glenn Freemantle, (Supervising Sound Editor/Sound Designer), Gillian Dodders (Supervising Dialogue/ADR Editor) and Ben Barker, (co-supervising sound editor) discuss how the sound design evolved on the mix stage, building up chaos with loop group, and their creative use of silence.
