The new This Is Spinal Tap sequel movie is getting two more famous cameos after Deadline reported that Metallica’s Lars Ulrich and Red Hot Chili Peppers’ Chad Smith will be entering the popular mockumentary’s sequel.

Ulrich and Smith will be joining an already-stacked lineup of musicians appearing in the film, including Paul McCartney, Elton John, Questlove, Garth Brooks, and more. The main cast of actors (Christopher Guest, Michael McKean, and Harry Shearer) will be reprising their roles. Fran Drescher will be returning as the fictional band’s publicist. Finally, director Rob Reiner will be returning — as he is leading the production taking place in New Orleans currently.
