I am well excited about the new film, but wonderd something as I read the lost world was meant to be another island. If so how did the dinos get there? Also is the 3rd film the original island?
I was under the impression they were all set of different island (although the first 2 could have been the same island) Ingen had a string of island near each other i think e.g One for development and research, A nursery, The tourist Park, and maybe some more, But after the first movie they all escaped from the fences on each island and overtook the islanRAB, killing the employees.
As I understand it there were two islanRAB, both of which where they raised dinosaurs but one was a kind of staging area and the other was for the park.
Site B was where the dinosuars were tested and allowed to run free. Isla Nublar was just a show where the park was built. All testing and research was carried out on Site B.
If you read both of the books by Michael Crichton this will become clearer.
