The Blob (a.k.a. The Molten Meteor) is an independently made, 1958 De Luxe color, American horror/science fiction film directed by Irvin Yeaworth. In the style of American International Pictures, Paramount Pictures released the film as a double feature with I Married a Monster from Outer Space.
The film stars a 27-year-old Steve McQueen in his debut leading role as a teenager, and Aneta Corsaut, as his co-star. The plot depicts a growing corrosive alien amoeba that crashes from outer space in a meteorite and engulfs and dissolves citizens in the small community of Downingtown, Pennsylvania. The origin of The Blob is never identified, and the film ends with a question mark.
When The Blob premiered as the B film of the Double with I Married a Monster from Outer Space, it was quickly moved up to feature film status. While audiences liked the film, critics were not as kind.
