Though film studios would never let it happen to their valuable franchises and intellectual property today, sometimes the cinema of the past slipped into the public domain. Often it was because of a lack of copyright notice, or a dispute over ownership, or some other legal mixup, but for whatever reason these films just floated out into the ether, where they were eagerly snatched up by drive-in cinemas, late night TV broadcasts, various home video distributors and now the web. Unfortunately, that's sometimes meant that the quality of the films has been compromised, but it also means movies at our fingertips, and around Halloween, we'll take all the horror flicks we can get.
In the gallery below, you'll find links to 10 films that, one way or another, hit the public domain. They range from true genre classics to B-movie cornball fun, and they're all just waiting for you to dim the lights, make some popcorn, and have yourself a little midnight movie marathon.
