A Beginner's Guide to Snuff is a 2016 horror comedy directed by Mitchell Altieri.
The film starts where Dominic and Dresden take auditions for an actress without giving them much clue as to the project.
Instead of informing her and hiring her, they decide to kidnap her and record all moments to capture genuine footage.
Things turn for the worse for the two brothers when they discover that Jennifer has freed herself and now has a gun on them.
Towards the end she kills them both and then the complete film is shown to be released on Christmas Eve as she promised to make them famous.
