There's another theory I have about JP3. Spielberg and Johnston are very close friends. You think that Spielberg would let him direct the third one with the little plot it had? Well, maybe he did. But here's what I think. I think there is MUCH more going on in JP3 than meets the eye. This may sound silly at first, but it does work: Billy. Ah yes, Grant's "apprentice" if you will. He was up to something on the island. Taking pictures of the embryo tanks, stealing velociraptor eggs, MANAGING to be rescued by the military EVEN THOUGH the pteranodons chased him DOWNSTREAM meaning that Grant and Co. would have beat Billy to the shore. Fishy? Very. It may be a plot hole, but I'm thinking Billy had a transmitter with him. Think about it. He was so anxious to get on the island. When Paul asked Grant to go with them to dinner, Billy basically made up Grant's mind for him. "Sure, we'd love to." "Ah that's terrific." Not only that, but about the raptor egg thing...uh, right. You don't steal dinosaur eggs to sell to someone on the mainland. He told Grant he was going to get money from them for profit for thier research, but who's he to sell them to? A museum? What would happen if the eggs hatched in the museum? Sure, they could inject a formula into the egg to kill the animal, but still. I just didn't believe that at all. Also, I remember the actors saying that Steven was NEVER on set, and that his absence really weirded them out. I think that Spielberg pretty much told Joe to throw in a character that would end up being an agent for INGEN or something, maybe to tie on with JP4. Spielberg said he has a great idea for the next one, better than the original. I just think there was more to Billy than meets the eye. Could I be wrong? Oh, definetly. I even doubt there is that much to it. But it would have been smart of the scriptwriters and it would definetly add a cool twist to the next one.
