In 1977, the film was purchased and colorized by Luigi Cozzi in a terrible way of a old negative print.
In 1977 Italian filmmaker Luigi Cozzi released a modified and colorized version to magnetic band and sensurround theaters in Italy. Originally, Cozzi planned to re-release the original 1954 Godzilla (without the Raymond Burr footage) but was unable to secure the rights from Toho. Instead, he was sold the Americanized version. Since the film was in black-and-white, regional distributors in Italy refused to release it. In order to release Godzilla, King of the Monsters, Cozzi hired Armando Valcauda to colorize the entire film, frame-by-frame, using a process named "Spectrorama 70". This process consisted of applying various colored gels to the original black-and-white footage. This resulted in it becoming one of the first colorized black-and-white films.
