King Kong was producer Dino De Laurentis . He threw a lot of money at this turkey. The movie wasn't the mega blockbuster he thought it would be. It made twice as much money it cost to produce at the box office but ol' Dino didn't make out like a bandit at the box office.In an effort to cut down on production costs, Dino tried to get Mario Bava to do the special effects (Bava is a master at using smoke and mirrors) but he declined and with with his protege Carlo Rambaldi. But in the end he used a young Rick Baker to not only handle most of the effects but he wore a gorilla suit when all of the stop motion miniatures cost too much. But it wound up costing even more for the complex suit that Baker designed.
The direction was ham fisted, the special effects were terrible (they should have stuck with stop motion puppets instead of some clown in a gorilla suit) and the finale was a joke. To top it off, the running time was well over two hours (the bad direction and pacing made it feel like five hours). The changes to the original plot and story were unnecessary (that's what ruins a lot of these remakes, don't fix what ain't broke people). You expect a movie that has the special effects crew of Rick Baker would have better effects than the ones on display.
A shame really, after all that money they threw at this production you'd think they would have put on a better show. The only thing cool about this movie was the original theatrical poster. It shows stuff that has nothing to do with the movie. If it did this movie would have been watchable. Instead it's an example of what happens to a production when you have a lot of money and no discernible talent behind the camera. Like Hollywood productions today.
