In regards to whether co-writer and director of the franchise, Robert Zemeckis, has previously stated he will never make a fourth movie . . . The time is ripe and he'd capture a whole NEW audience... If Jurassic Park creators can do so can Zemeckis... Or to paraphrase a line from his movies: "Hello? Hello? Anybody home? Huh? Think, Zemekis. Think! Wake up and realize that you'd be crazy NOT TO want to do another! Right? I said Right!"
Even Doc would be aghast!!
