This Island Earth is a 1955 American science fiction film from Universal-International, produced by William Alland, directed by Joseph M. Newman and Jack Arnold, that stars Jeff Morrow, Faith Domergue and Rex Reason. It is based on the eponymous 1952 novel by Raymond F. Jones, which was originally published in the magazine Thrilling Wonder Stories as three related novelettes: "The Alien Machine" in the June 1949 issue, "The Shroud of Secrecy" in December 1949, and "The Greater Conflict" in February 1950. The film was released in 1955 as a double feature with Abbott and Costello Meet the Mummy.
Upon initial release, the film was praised by critics, who cited the special effects, well-written script, and eye-popping Technicolor prints as being its major assets. In 1996, it was edited down and lampooned in Mystery Science Theater 3000: The Movie, a spin-off of the popular syndicated movie riffing television series Mystery Science Theater 3000. Scream Factory has released the film on Blu-ray with a new 4K scan of the interpositive, featuring two aspect ratios: 1.85:1 and 1.37:1
