Studio 666 is a 2022 American comedy horror film directed by B. J. McDonnell from a screenplay by Jeff Buhler and Rebecca Hughes, based on a story by Dave Grohl, who stars, alongside his Foo Fighters bandmates Nate Mendel, Pat Smear, Taylor Hawkins, Chris Shiflett, and Rami Jaffee, portraying fictionalized version of themselves.

In 2019, the Foo Fighters—Dave Grohl, Taylor Hawkins, Rami Jaffee, Nate Mendel, Chris Shiflett, and Pat Smear—are pressured by their manager Jeremy Shill to overcome their writer's block and record a new album.

Later, a delivery man named Darren, who had earlier tried to give Grohl a demo tape, is decapitated outside the manor by an unknown figure with hedge clippers.

Shiflett attempts to escape but he has his head smashed with the grill cover and is stabbed repeatedly in the neck, before the figure is revealed to be Grohl.

Mendel and Smear free Grohl from the possession, and the souls of the Dream Widow band members send the demon to hell.

Hatchet III filmmaker B. J. McDonell directed the film, working from a script written by Jeff Bulher and Rebecca Hughes, based on a story from Grohl inspired by their experiences recording their tenth album.
