Widely remembered as one of the genre’s early B-movies, the original The Blob film depicts teenagers in a small Pennsylvania town who are up against a growing alien substance that landed on Earth in a meteorite.

Starring a young Steve McQueen in his first leading role, the film is a classic to many a genre-fiend. There have been talks of a future remake (beyond the unnecessary 1988 version), but only time will tell.
