All the movies listed below are commonly believed to be in the public domain. Public domain refers to the body of creative works and knowledge in which no person, government or organization has any proprietary interest such as a copyright. These works are considered part of the public cultural heritage and may be freely used by all. However please be aware that although the movies may be in the public domain, the summaries are not. I wrote them, they are copyright protected, and should not be copied and used elsewhere.
The links below lead to pages that contain more information about the movies, and there is a player at the bottom of each page so that you can watch the movie, for free.
