I guess that I should start out by telling my reader that I have never seen the movie King Kong, however I would also like my reader to know that I think I know the plot line a little bit. In Peter Jackson's new version, apparently King Kong was also genetically engineered when the old guy from Jurrasic Park was making dinosaurs. Then he let the monkey live on the island with the dinosaurs in the park.
Also , Jackson has used an idea from his past movie (actually three and they were about walking) and apparently put zombies in the film. (or maybe not zombies, but people that look like zombies)
