For cinephiles, Green Room poses several questions. Audiences might wonder how the potpourri of performers came together for the film, or how some of its startling sequences were filmed. Behind-the-scenes facts from the movie's development reveal some interesting answers.

The Director Made A Short Version First

Green Room is one of Jeremy Saulnier's highest-rated movies. The director's plans for the film came before its development began to take shape. Saulnier told Slash Film that he made a short film taking place in a green room over six years before the full-length feature was released.

However the short movie used a metal band and Saulnier said it was much more "hammy," and closer to a dark comedy. With Green Room, he wanted to do the project "the right way."

The Violence Was Meticulously Curated

Saulnier told interviewers that each moment of violence in the film was looked at with scrutiny. He said the moments of gore are "about these kids, these band , transition into killers."

The Director Used To Play In A Punk Band
