Let's face it. Today, we're spoiled. Any movie we want to see is readily available through some means (even if it's bootleg), there's nothing that can stop an avid movie fan from seeing the film of their choice, no matter the rarity.
However, prior to streaming, Blu-Rays, and DVDs there was laserdisc, VHS, and BETA - but prior to that - there was 8mm film (actual, physical film -- GASP!) That's right, you needed an actual projector to play these. The early 8mm reels weren't even in sound or color (though later ones would be) and let's also keep in mind that the average 8mm film would be anywhere from three to eleven minutes, depending on the reel size. Yep, you didn't even get to see the whole film.
We now present to you the only way you could have watched Godzilla vs. The Thing back in the 1960s, aside from seeing it in the theater or owning the entire 35mm reel. Sit back, grab some popcorn (a small bag, because this is short) and enjoy nearly three whole minutes of a classic Godzilla film, in glorious non-definition.
