Prior to the release of Indiana Jones and the Kingdom of the Crystal Skull, my kids took an interest in the series after my son got a set of Indiana Jones Legos.
They watched all the movies for the first time, about 20 years after the last one was made. They loved them. (They haven't seen the new one yet, but I'm hoping to take them next weekend.)
One day, my wife pulled up a screen shot from the new movie on her computer. My 10 year old daughter, looking over my wife's shoulder, saw the picture of Harrison Ford and said, "Eh, it's just an old guy trying to be Indiana Jones."
