Outside of working with David, Sefi’s career has been incredibly varied, working in film doing everything from sound mixing to over-dubbing and foley art, which is the creation of sound effects.
Speaking of his work in foley, Sefi explained some of the stranger sounds he has had to create, and how directors he has partnered with felt about them.
He said: “I was working once on a documentary where there was a shot of someone slaloming on a mountainside, and we couldn’t really find something [a sound for it].
“We were looking for kind of washy sounds and they were not distinct enough for what the director wanted.
“We tried various stuff, and then the director went for lunch and he came back and I’d found something and I put it onto the movie, and he said, ‘This is amazing. What is this? It works so well with the slaloming.’
