Warning: Suggested reading before watching the trailer
Ghost Stories is a British horror film from creators Jeremy Dyson and Andy Nyman. Jeremy Dyson is known for the British comedy series The League of Gentleman and Andy Nyman is an actor who is known for his work with illusionist Darren Brown. Together Jeremy Dyson and Andy Nyman wrote a stage play called Ghost Stories in 2010. It is about a Professor of Parapsychology telling three stories of people who claim to have had an experience with the supernatural. And that's all I can tell you. The marketing for the play has no production photos, just shocked reactions of the audience instead. At the end of the play, the audience is asked to, "Keep the secrets of Ghost Stories." In 2017, Ghost Stories was adapted into a movie directed by Jeremy Dyson and Andy Nyman and premiered at the London Film Festival in October.
Below is one the trailers for the movie. If you are a horror fan like myself and intend on seeing Ghost Stories, based on the, "keep the secrets of Ghost Stories" announcement at the end of the play, I recommend that you not even watch the trailer. I do not think this and other trailers will actually reveal too much, but don't take my word for it, because I'm certainly not going to be the one to find out for sure.
Ghost Stories was released on April 6th in the United Kingdom, and will be released on the 20th (420!) in America.
It should go with out saying, no spoilers in the comment section with out warning, please.
