All About Evil is a 2010 American black comedy horror film written and directed by Joshua Grannell.
When his best friend Judy Ariel Hart disappears, Steven Thompson Thomas Dekker discovers the truth about Deborahs actions and tries to stop her as she attempts to murder the audience during the premiere of her featurelength film, which is about the audiences deaths. Steven manages to rescue Judy and the audience escapes, killing Mr. Twigs and the robber as they try to stop them. Deborah kidnaps Stevens mother and takes her to the roof to kill her where Steven confronts her. When Steven points out how disappointed her father would be, Deborah gets emotional, allowing Stevens mother to break free and stab her in the neck with her own knife. Steven then pushes her off the roof to her death.Most of the audience survives and escapes and when the twins come out, the police try to arrest them. Instead of surrendering, they turn on each other and stab each other repeatedly, killing each other. The news talks to Steven about Deborahs films and the possibility of her actions becoming a film, which he doubts will happen, commenting that if it were, Deborah would rise from the dead by now. As he leaves, a worker causes Deborahs body to move and she seems to stare right at him, freaking him out slightly. ........
