Fans buying a disk or digital copy can watch a version of the movie that centers on John Williams' score.

Fans of Star Wars: The Last Jedi buying the movie for home use will get access to a never-before-seen version. Both digital and physical purchases will unlock access to a cut of the movie where the only audio is John Williams’ score.

The music-only edit was revealed by Last Jedi director Rian Johnson on Twitter, who called it his favorite (“kinda hidden”) special feature. There is a catch, however; to access it, customers will have to sign up for the Movies Anywhere app, the Disney-backed digital movie aggregator which is the exclusive home for the score-only Last Jedi.

Williams’ score for The Last Jedi has been much lauded by fans of his work, and the Star Wars series as a whole — a fun fan-made podcast series released around the movie’s theater run looks in-depth at the choices made by the composer, and is a recommended listen — and, with Williams teasing a potential retirement from the franchise following next year’s Episode IX, releasing a version of Star Wars: The Last Jedi where his work is the only audio available feels like a thank you for decades of work from the studio.

Star Wars: The Last Jedi is available digitally now, with Blu-Ray release on March 27.
