On October 31, 1992, an extraordinary program called Ghost Clock was broadcast on the British television channel BBC1. TV presenter Michael Parkinson investigated paranormal activity in a London house live. The residents of that house complained of mysterious knocking sounds and the appearance of a ghost. TV presenter Sarah Green reported live, and there were experts in the studio watching what was happening. Viewers, by the way, were invited to call the real BBC number and share their observations. It didn't take long for the ghosts to appear: strange figures and objects moving on their own flashed into the frame. The presenters later reported that the telecast united millions of viewers in a huge séance, so that the ghost allegedly had the opportunity to enter the BBC studio and take possession of the body of the main presenter of the program, Parkinson. Unfortunately, contrary to the hopes of fans of the supernatural, Ghost Hour turned out to be a pre-produced horror film. Screenwriter Stephen Wolk conceived it back in 1988 as a multi-part project, but later decided to present the story in the format of a single television documentary for Halloween. For authenticity, real BBC presenters were brought in, TV cameras, pre-recorded phone calls and deliberately sloppy camera work were used. The photographs were taken in the summer, so the windows of the house were covered with black cloth, creating the illusion of night. Although the show was labeled as an artistic production, some of the 11 million viewers accepted what was happening as reality. The BBC's phone lines were flooded as people tried to find out what happened to Sarah Green and parents complained of frightened children.
