First released to Japanese theaters in March of 1968, Gamera vs. Viras was a middling commercial success. It was picked up by American International Television that same year and after some editing was released over here as Destroy All Planets. And yes, the same year Toho released Destroy All Monsters!, so the name that the Americans came up with for their version of Gamera vs. Viras screams of rip-off. I guess you can't really blame them for trying to feed off some of the positive publicity that the Godzilla movie was receiving at the time.
