Hans Zimmer is a movie soundtrack legend, having scored over 100 films and TV shows, including The Dark Knight and Man of Steel. Yet even a mega-composer like Zimmer still gets starstruck. In a recent interview, Zimmer named his own personal favorite film composer: Radiohead’s Jonny Greenwood.

Greenwood has composed soundtracks for multiple Paul Thomas Anderson films: There Will Be Blood, The Master and Inherent Vice. Next, Greenwood will compose the score for Anderson’s Phantom Thread.

But don’t you dare call him a “workaholic.” In an interview with /Film, Zimmer once said:
