Whilst on holiday in England, I hopped on the train to Twickenham Studios, just outside London, to have a chat with James Mather, who was sound supervisor of the last four Harry Potter films as well as having worked on Mission Impossible: Rogue Nation, Clash of the Titans and countless others. James has been working in the British industry for decades now, and he was kind enough to invite me to his studio for an interview on the eve of 2019. James talked about some really interesting stuff including how they approached the changing tone of the Harry Potter franchise in the soundtrack, his methodology when working on action sequences and how picture editors and the sound department can learn from each other.
