protection plus the remainder of the final calendar year. Although 95 years of protection was possible for works published in 1925, protection beyond 28 years required, at the time, a renewal with the US copyright office during the 28th year. The copyright of The Lost World was not renewed. Any elements of the film that were not released in 1925, and were not released during the lifetime of the movie's producer, have 70 years of copyright protection after the death of the producer. The producer, Earl Hudson, died in 1959, so any such film elements will enter the public domain on January 1, 2030.
