Beginning her career at Theodore Music, she worked across a broad range of music supervision projects before specialising in music editorial for film and television. Her diverse musical background allows her to collaborate closely with composers, editors and directors throughout the editorial process, combining technical precision with a deep understanding of how music shapes character, emotion and narrative.

Marnie has worked across a range of productions including Disney’s ‘Doctor Who’, scored by Murray Gold; HBO’s ‘Industry’, scored by Nathan Micay; Sky’s ‘Sweetpea’, scored by Isobel Waller-Bridge and Jonny Woodley; BBC’s ‘The War Between the Land and the Sea’, scored by Lorne Balfe; ‘Mr Loverman’, scored by Speakers Corner Quartet; ‘Frauds’, scored by Alex Baranowski; and, more recently, Netflix’s ‘Grown Ups’, scored by Stephen Rennicks.

A First Class BA (Hons) graduate in Electronic Music: Production and Composition, Marnie brings the perspective of both a music producer and music editor. She is particularly drawn to projects with distinctive sonic identities, collaborating closely with filmmakers to create music that feels emotionally authentic, creatively ambitious and seamlessly integrated into the picture.
