FILM 1515: THE VISIT
TRIVIA: According to statements made on Twitter, M. Night Shyamalan prepared three different cuts of the film. One that was "pure comedy", another that was "pure horror", and a final one that "fell somewhere in between."
M. Night Shyamalan used his fee from his science-fiction-adventure movie After Earth (2013) to self-produce the film in question. In his own words, this was "an attempt to regain artistic control" after his recent movies had been denied final cut, and were even taken away from him in post-production.
