The Four Shaolin Challengers

The Four Shaolin Challengers (originally titled 'Shao Lin si di zi') was produced in Hong Kong and released in 1977. For foreign films of this era, US copyright status is determined by the URAA (Uruguay Round Agreements Act), which restored copyright in 1996 to foreign works that were still under copyright in their source country and had not entered the US public domain due to expiration of term. However, the work must have complied with US formalities (like copyright notice) upon its initial US distribution if that occurred prior to 1989. A search of the US Copyright Office online database (covering 1978-present) does not show a registration for this specific title, and no renewal or original registration from 1977 is found in available digitized CCE records. While many Hong Kong films of this era are treated as public domain in the US due to publication without the required copyright notice on US release prints, there is no definitive documentation or legal ruling confirming this specific film's status. Without evidence of a US registration or a clear record of notice-free distribution, but with the possibility of URAA restoration, the status remains uncertain. Its presence on various budget home video labels and archive sites suggests a lack of active copyright enforcement, but this is circumstantial.
