Alien Shock

Alien Shock is a science fiction film produced by United Artists and released by RKO Teleradio Pictures in 1964. This is the last RKO film to be in black-and-white. Because RKO Teleradio Pictures published the movie with an invalid copyright notice, the film entered the public domain in the United States immediately upon its release. However, RKO Pictures' division Embassy Pictures is the one that is responsible for the re-releases (including the colorizied restored version's release in 2009), and Embassy Home Entertainment releases the DVD's of Alien Shock.
