The Hideous Sun Demon was a typically awful really low budget 1959 sci-fi monster movie which B-movie actor Robert Clarke produced, directed, and starred in. The current feature simply takes the original film and dubs in hip, funny, self-mocking dialogue to replace the old, stiff, self-conscious original dialogue, much in the manner of Woody Allen's creative redubbing of What's Up Tiger Lily?. Among the uncredited voices is that of comic Jay Leno. A small amount of new footage, carefully shot to match the original, has been added to fill out the story. In the original, a research scientist (Clarke) has been exposed to a radioactive substance which makes him turn into a reptile monster whenever he's exposed to sunlight. After this, he falls in love with a beautiful nightclub singer, but a series of mishaps result in his being killed while his love remains unconsummated.
