I will admit when I was hearing some talk about a trailer for Stage Fright I thought someone remade the 87 film by Michele Soavi. However that is not the case and this Stage Fright is I believe a film based on found footage within a film. I do not know if I am explaining that right but I think you will get it when you check out the trailer. The film is supposed to be released in October so I will definitely keep my eyes out for it so I can check it out. You can watch the trailer down below and also be sure to check out the film's Facebook page for updates and more information on the film.
