List of films in the public domain in the United States

This is a list of films in the public domain in the United States. A number of films exist that certain cited sources believe are in the public domain in the United States. Being in the public domain refers to cinematic, dramatic, literary, musical, and artistic works that no government, organization, or individual owns, and as such is common property.

Note: Films in this list may incorporate elements from other works that are still under copyright, even though the film itself is out of copyright.

There is no official list of films (or other works) in the public domain. It is difficult to determine the public domain status of a film because it can incorporate any or all of the following copyrightable elements:

Film copyright involves the copyright status of multiple elements that make up the film. A film can lose its copyright in some of those elements while retaining copyright in other elements. Experts in the field of public domain sometimes differ in their opinions as to whether a particular film is in the public domain.

The use of music in a film can cause uncertainty with regard to copyright. As of 2010, it is not known whether the use of music in a movie constitutes publication of the music for the purpose of copyright. Unpublished works are treated differently from published works under US copyright law.

Judges, too, differ in their interpretation of the laws governing copyright protection. The United States is a “patchwork quilt” of inconsistent copyright rules in different federal judicial districts. The courts of one jurisdiction are not obliged to follow the decisions of another. The Supreme Court of the United States (which could resolve those inconsistencies) very seldom decides copyright cases, and then only when an important principle is involved.

If a film appears on the list below, there is a high probability it has lost some or all of its United States copyright protection or in the case of U.S. government films, was never protected by copyright.

There is no single method for determining if a film, or parts of it, is in the public domain. There are several methods that can be used to document a film’s public domain status. These include the following:

Prior to 1988, all motion picture films published after 1909 with a copyright notice where the 28th year of copyright would occur before 1988, had to be registered and before the 28th year, the registration had to be renewed, or the copyright for the film would expire and it would enter the public domain. This would apply to all films registered for copyright prior to 1960. Copyright renewals became optional in 1988.
