A really ugly-faced version of King Kong takes on a goofy-ass Robot Kong who is controlled by an evil Dr. Who. The plot revolves around making these big apes dig up some precious element which is dumb. This is basically a Godzilla movie without Godzilla in it. It's also a sort-of sequel to KING KONG VS. GODZILLA though they never refer to that movie so maybe it's not. It was also produced by Rankin & Bass who did all those animated Christmas specials and stuff like MAD MONSTER PARTY and this movie was a tie-in to their KING KONG cartoon show which makes sense because this is a very cartoon-ish film. Mecha-Godzilla would show up a few years later which I assume was inspired by Mecha-Kong here. Good for a laugh if you're a big stupid monster fan.
