Film Studies For Free knows from tireless study of its visitor statistics that one of the internet search phrases that most often brings readers to this site is 'free online films'. So, for those (evidently numerous) folks who haven't yet discovered the very best gateway to and repository of thousands of free and legal online films, including many important feature-length films (like Fritz Lang's 1931 M - Eine Stadt sucht einen Moerder - see still images above; please click HERE for the online film with English subtitles), here is the link to the website of your search engine dreams: the Moving Images section at the Internet Archive (a site you should explore for lots of other reasons, too). All Internet Archive material is in the Public Domain, so it's a must-promote resource for an Open-Access advocacy website like Film Studies For Free.
So you can see the full scope of its rich offerings, below are the subsections that make up the Internet Archive Moving Images website area:
Animation & Cartoons Arts & Music Computers & Technology Cultural & Academic Films Ephemeral Films Movies News & Public Affairs Non-English Videos Open Source Movies Prelinger Archives Spirituality & Religion Sports Videos Video Games Vlogs Youth Media
