DVD Savant has a review of the newly-released, "Five", a 1950 post-nuclear apocalypse movie by Arch Oboler.
Oboler is best known today as the man behind "Bwana Devil", the movie that started the 1950s 3d craze. However, fans of old time radio know him for his work on "Lights Out", an influential radio mystery series.
Oboler's film work is mostly forgotten, but is certainly worth checking out - his parody of mass media, "The Twonky", from the early 1950s sounds very intriguing. Besides the subject matter and style of Oboler's movies, which used some radio techniques for sound, the movies are interesting technically. "Five" was the first movie to use magnetic sound recording and was the first movie to use television as promotion for the release. His later film, "Domo Arigato", was the first to use single-lens 3d projection, the format used for movies in the 1980's 3d revival.
