Earthquake!

EARTHQUAKE - 1974

I was formally instructed by my parents when I asked them about this movie to say that "they're too young and hip to remember such an old movie", haha.

Anywho, this movie was very important and memorable when it came out, because it used and manipulated the atmosphere within the movie theatre to really envelop the audience. The deep base sounds and sound effects were emitted through speakers on the floor, causing the ground to feel as though it were shaking - which was important since the whole movie was centered around a massive earthquake. This was a new experience that ended up catching many people off-guard, and led them to panic in fear of a real earthquake occurring during the film.

A new sort of "special effects" was also introduced with this film, where pristine, exact scale versions of the cities were used when it was needed. In order to really make it look like the city was being torn to bits by the shaking, without actually destroying an actual city, a small-scale 3D model was built and reverberated to the point where it crumbled the way it would've should it have been real. This helped the audience really get fascinated and struck in awe by the magnitude of what was happening in the film.
