All About Evil is a 2010 American black comedy slasher film and marks the feature film directorial debut of Joshua Grannell, who also wrote the script. The film stars Natasha Lyonne as an unhinged theatre owner who begins making snuff films and screening them at her decrepit San Francisco theater—presenting them as fictional works—in order to prevent the theater from going bankrupt. The film was shot at the Victoria Theatre in San Francisco and also stars Thomas Dekker, Cassandra Peterson, Noah Segan, and Jack Donner. The soundtrack featured a score by Vinsantos and songs by artists such as The Vanishing. Grannell based the film on his 2003 short Grindhouse; the film's title, All About Evil, refers to the 1950 drama film All About Eve. All About Evil premiered at the 2010 San Francisco International Film Festival and Grannell independently released the film to DVD that same year. The film was later given a new home video release in 2022 through Severin Films.

When Tammy confronts her one night about selling the theater, Deborah flies into an unexpected rage and brutally stabs her to death in the lobby, just as a screening is about to begin. In a panic, Deborah rushes to the projection booth to start the film, but inadvertently screens security footage showing the murder she just committed. The patrons of the theater—among them, teenage film buff Steven Thompson—assume the footage to be a short film screened before the main feature, and are impressed by it. Mr. Twigs, a longtime projectionist at the theater who despised Tammy, helps Deborah hide Tammy's corpse in the theater's attic. The unhinged Deborah commits a second murder with the help of Mr. Twigs, this time of a theatergoer named Veronica, and films the act; in the footage, Deborah acts as a Victorian queen, while she and Mr. Twigs cut off Veronica's breasts with a guillotine. They screen the footage as a short film before another main feature, and it shocks the
