The 1976 mystery horror film “Burnt Offerings”, based on the 1973 novel of the same name by author Robert Marasco, was directed by Dan Curtis who, years before, had no idea what he was into.
In the film’s commentary, Curtis says that he actually read the novel “Burnt Offerings” years before he got the offer to direct this film. Interestingly, Curtis said that he hated the open-ended conclusion of the novel and, at the time, thought to himself that he would pity anyone who would attempt to make it into a movie.
Someone must have heard him because, ironically, years later when the offer to direct the movie version of the novel came to him, the first thing Curtis did was write an ending that he liked. And that ending, ladies and gentlemen, was the one featured in the film. Looks like Curtis was given such pity that he asked for years ago.
