Many are the websites that offer the possibility of watching movies on the web, although the vast majority do not have the necessary license to do so, so they are withdrawn after a short time.
This is not the case with films in the public domain, movie classics that are scattered on various specialized portals, thousands of titles that can be released without fear of breaking any law.
Here you have a series of sites, compiled in openculture, that allow us to have access to various feature films, documentaries and other works of the seventh art. Many of these videos are in the public domain, others are distributed for free, others have private licenses.… But all of them can be seen without having to pay anything.
