The Crawling Eye (1958) / Cosmic Monsters [The Cosmic Monster (1958) - Newspaper Ad

San Francisco Examiner - March 4, 1959

Although Bryan Senn's comprehensive and excellent resource guide and historical recap "Twice the Thrills! Twice the Chills!" Horror and Science Fiction Double Features, 1955 - 1974 gives a July 7, 1958 release date for this monstrous double bill, it did not open in the San Francisco Bay Area until March 4, 1959.

Both were British film adaptations of BBC serials that cast Forrest Tucker in roles for both films, to help sell the movie to audiences in the United States.

Of the two I have only seen The Crawling Eye, which remains a cherished childhood favorite of mine.
