YouTube is the world's largest video platform, but most people use it for short-form content and music videos. What they don't realize is that YouTube also hosts hundreds of full-length films — many of them excellent — available to watch for free.

Our selection this month includes independent films that never received theatrical distribution, classic titles that have fallen into the public domain, and recent releases that filmmakers have chosen to distribute through YouTube rather than traditional channels.

The best discoveries are the ones you stumble upon. Consider this your stumble.
