She's helped create some of the most popular and influential movie soundtracks of recent times - Pulp Fiction, Clueless, Boogie Nights and Baz Luhrman's Romeo and Juliet.
Now music supervisor Karyn Rachtman has plunged into something new - the soundtrack for a new ocean-science adventure game.
Beyond Blue is based on the much-loved BBC documentary series Blue Planet II and there's not a machine gun or a car race in it!
She'll also be talking about creating soundtracks at the upcoming Big Screen Symposium.
Lynn Freeman asks Karyn about the challenges of scoring a game soundtrack - and how you even turn undersea exploration into a game? .
