Ator l'invincibile 2 (released in English-speaking countries as Ator the Invincible 2, The Blade Master, Ator, the Blade Master, Cave Dwellers, and The Return) is an Italian film that was made in 1984. The movie was written and directed by Joe d'Amato. It stars Miles O'Keeffe as Ator, a man skilled in not only fighting, but in many other arts as well. It also stars Charles Borromel as Akronas, a wise ruler and teacher who is also called the Great One. Lisa Foster stars as Mila, the daughter of Akronas, and David Brandon as Zor — the principal villain of the film. The film was released in theaters as Ator the Invincible and later as Ator, the Blade Master. It received the name Cave Dwellers after it was re-edited by distributor Film Ventures International. It is the sequel to 1982's Ator l'invincibile and was followed by 1986's Iron Warrior. The movies were made to capitalize on the popularity of the Conan movies which starred Arnold Schwarzenegger.
The movie was featured in episode 301 of Mystery Science Theater 3000 (MST3K). O'Keefe was reportedly amused by the show's take on the film and called Best Brains (MST3K's production company) to personally request a copy of the episode. It is one of the most popular episodes of the series. The MST3K version of the movie is available in both VHS and DVD formats.
Mystery Science Theater 3000 (often abbreviated as MST3K) is an American cult television comedy series created by Joel Hodgson and produced by Best Brains, Inc., that ran from 1988 to 1999.
The series features a man and his robot sidekicks who are trapped on a space station by an evil scientist and forced to watch a selection of bad movies, often (but not limited to) science fiction B-movies. To keep sane, the man and his robots provide a running commentary on each film, making fun of its flaws and wisecracking (or "riffing") their way through each reel in the style of a movie-theater peanut gallery. Each film is presented with a superimposition of the man and robots' silhouettes along the bottom of the screen.
Series creator Hodgson originally played the stranded man, Joel Robinson, for five and a half seasons. When Hodgson left in 1993, series head writer Michael J. Nelson replaced him as new victim Mike Nelson, and continued in the role for the rest of the show's run.
During its eleven years, 198 episodes and one feature film, MST3K attained critical acclaim. The series won a Peabody Award in 1993, was nominated for two Emmy Awards (in the category of Outstanding Individual Achievement in Writing for a Variety or Music Program) in 1994 and 1995, and was nominated for a CableACE Award.
In 2007, James Poniewozik listed Mystery Science Theater 3000 as one of Time magazine's "100 Best TV Shows of All-TIME."
