"But actually theory is very practical. Gravity is a theory, for example. It allows you to predict that if you step off a cliff you will fall; you don't have to collect data on that."

I definitely felt frightened [on Skyfall], but never in danger, because they were always so careful about everything. Some of the driving, particularly on that road around the sheer-drop cliff was actually done by stunt driver Ben Collin, who is otherwise known as The Stig from the TV show Pop Gear. He's a brilliant drive, nonetheless, it was terrifying to be careening along when a wrong turn would mean a thousand-foot drop and you're not in control and you want to slow the car down.
