In the late 1970s, when one of the authors of this chapter was at an impressionable age, his parents took him for the first time to a movie theatre.

The epic music, accompanied by dazzling visuals and a delightful story, transported the young boy to a brand-new and brightly colored universe where just about anything seemed possible. When lights switched on and the credits appeared, our boy felt alive and bursting with energy. Indeed, as the movie ads had promised, he found himself believing that a man could fly.
