Gamera the Invincible is one of the worst, most shoddily-produced movies ever made. Doing a storyboard of the opening five minutes will show that the editor and director have Air Force planes flying directly towards each other (the "180 line" is crossed about a dozen times in the first three minutes alone!), differing numbers of passengers in the vehicles, a U.S. Air Force General who looks, acts, and sounds like some drunk they found in a Ginza gutter, etc. And that's just the first few minutes! The whole thing looks and sounds as bad as any movie an unimaginative child might have shot with a Super-8 sound camera (notorious for being out of sync), but most children could have probably built better models than the ones used in this sub-infra-Roger-Cormanesque piece of poo.
Amazingly, the movie gets WORSE as it progresses! Stay far, far away from this dreck-
