"If you watch a movie from between the end of the Second World War and the mid-1970s, whenever anyone steps out in a white lab coat, they're there to offer a solution. They're there to tell you how the laser's going to save the day. They're going to give you James Bond's array of tools. After about 1975, whenever the man in the white lab coat steps out, it's to come up with some crazy idea that's going to bring ruin on everybody. "Let's clone dinosaurs!" And the last we see of him is disappearing down the gullet of the Tyrannosaurus rex."
