Hell's Bells (film)

This work is in the public domain in the United States because it was published before January 1, 1930.

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 1972, so this work is in the public domain in countries and areas where the copyright term is the author's life plus 52 years or less. This work may be in the public domain in countries and areas with longer native copyright terms that apply the rule of the shorter term to foreign works.
