“ Copyright law abroad tends to consider the following people authors of a film:
The principal director The screenwriter, and/or other writers of dialogue The composer/lyricist (if the film is accompanied by sound) The cinematographer By extension, the authors of any works that may serve as the basis for a film's plot The longest-living of these authors died in 1968, so this work is in the public domain in countries and areas where the copyright term is the author's life plus 55 years or less. ”
