Bill & Ted Face The Music is giving fans of the film franchise a chance to be in the film.

Writer Ed Solomon announced on Twitter Tuesday (5) that to finish the film, fans are being asked to submit videos of themselves rocking out to a provided guitar riff as part of the “Party On with Bill & Ted” campaign. 

“The producers would like to invite you to be a small but most excellent part of our movie” reads the opening statement on a website devoted to the campaign. The site includes a 30-second recording of the aforementioned guitar riff and prompts fans to “film yourself, family, friends and even your pets rocking out!” Fans are encouraged to either “Learn the tempo or play the demo in the background for yourself,” though music skills are not necessary, mentioning that “It’s okay if you can’t play.” Basically, if you can make your content interesting, keep the camera steady and don’t break any laws, you have a shot at your video being in the film. Submissions must be in by May 20 to have the best chance of being considered.

Face The Music is the third film in the Bill & Ted franchise that started with 1989’s Bill & Ted’s Excellent Adventure and followed with 1991’s Bill & Ted’s Bogus Journey. The film finds the now middle-aged titular characters (featuring Alex Winter and Keanu Reeves reprising their roles as Bill S. Preston Esq. and Theodore “Ted” Logan, respectively) on a new adventure after “a visitor from the future warns them that only their song can save life as we know it and bring harmony to the universe.  Along the way, they will be helped by their families, old friends and a few music legends.”

Bill & Ted: Face The Music is slated to hit theaters in the summer of 2020.
