The Flame Barrier

The Flame Barrier was a US production released in April 1958. Under the Copyright Act of 1909, works from this era were granted an initial 28-year term of protection, which could be extended for a second term if a renewal was filed with the Copyright Office during the 28th year. For a 1958 release, the renewal window was open in 1985 or 1986. A search of the Stanford Copyright Renewal Database and the US Copyright Office CCE records (via Project Gutenberg and U Penn) shows no renewal registration for this title. While the film was originally registered for copyright on May 9, 1958, under LP10787 by Gramercy Pictures, Inc., the failure to renew the copyright at the expiration of the first term resulted in the film entering the public domain in the United States on January 1, 1987. This status is corroborated by the film's presence in the 'Film Superlist: Motion Pictures in the U.S. Public Domain' by D. Richard Baer, which lists it as a non-renewed title. The film is frequently included in public domain collections and is available on various grey-market and archive sites without copyright challenge. Note: generated without live web grounding (the grounded research engine was unavailable). Verify the cited sources independently before relying on this determination.
