I had an interesting comment the other day.
I'd stopped at a gas station and a guy in a early 70's Mustang came over and said, "Hey, That's the car that was used in That movie!"
When he stumbled on the name of the movie I told him, Back to the Future.
He replied, "No that's not it. It was that James Bond movie where the car becomes a submarine."
I tried to explain that's not the same car. He advised me to watch the James Bond movie again and then I'd see it was.
