Captain
A successful combination of sincere horror and sly camp from director Irvin S. Yeaworth, Jr.
Steve McQueen (in one of his first roles) plays a teenager who runs afoul a shapeless alien which emerges from a hollow meteorite and hungrily engulfs everyone it touches.
The more it eats, the bigger it gets, until finally it surrounds a trailer-sized cafe with Steve and his girl friend (Aneta Corseaut from "The Andy Griffith Show") trapped inside.
The blob's first victim is played by Olin Howlin, the colorful old drunk from Them.
The Blob manages to be downright spooky, despite being shot on a low budget and possessing a funny rock-and-roll title theme which makes no attempt to put anyone in the mood for a scary movie. It was one of the few color science fiction films of the 1950s, and the memory of that bright red gelatinous mass pursuing its victims is one of the 1950s' most treasured mental souvenirs.
Japan released their own blob-monster movie the same year, The H-Man, directed by Inoshiro Honda (Japan's Jack Arnold), who gave us Godzilla, Rodan, and many others.
