Monster a Go-Go

Monster a Go-Go was originally filmed in the early 1960s by Bill Rebane, but was left unfinished until Herschell Gordon Lewis purchased the footage, added new scenes, and released it in 1965. Under the 1909 Copyright Act, works published between 1964 and 1977 are subject to automatic renewal; however, they still required a valid copyright notice upon publication to secure federal protection. Research into the Film Superlist: Motion Pictures in the U.S. Public Domain (1960–1969) and the Library of Congress Catalog of Copyright Entries (CCE) fails to show a timely original registration for this film under this title. Furthermore, the film is widely documented as having fallen into the public domain due to the lack of a proper copyright notice on the original release prints. It has been a staple of public domain distributors for decades, appearing in numerous budget collections from companies like Alpha Video and Mill Creek Entertainment, and was famously featured on Mystery Science Theater 3000, which frequently utilized public domain titles to avoid high licensing fees.
