Due to the fact that Night of the Living Dead slipped into the public domain many years ago, anybody, anywhere, is legally allowed to release their very own DVD of the film and profit off of it. As you can imagine, many many people have taken advantage of this over the years, which has resulted in over 30 different DVD releases of the horror classic, in Region 1 alone. Various bells and whistles have been added to some to seperate them from the pack, including color, 3D, laugh tracks, and even scene additions. Here are, to the best of my knowledge, the cover arts of each and every one of those releases, many of which you have probably come across at your local video store. I should note that I have only included the releases of Night of the Living Dead by itself - there are probably at least a few dozen more releases of it packaged with various other titles. Leave a comment and let me know which art is your favorite!
Night of the Living Dead has even been popping up on Blu-ray lately, which you can read more about on Blood Sprayer.
