The Invisible Ray(Film, 1920)

The Invisible Ray is a 1920 American science fiction film serial directed by Harry A. Pollard. Early press accounts cited the "scientific foundation of the plot. In this respect the production differs from other serials. Fact and not fancy governs the action throughout. The plot is based on a scientific investigation made by the author of the serial, Guy McConnell, investigation for several research institutions and for the Chemical Division of the United States Department of the Interior." The film was also lauded for its special effects. According to a report in The Moving Picture World, "Mighty buildings, rocks and forests are set afire and exploded. The expert application of clever photographic devices makes the picture appear strikingly realistic." The serial is now considered to be lost. ()
