Part 1 of the Hero’s Journey:
The beginning most likely takes place in the here and now, the Ordinary World.
It often introduces us to the problems, the boring reality, and the characters merely hover in it. After all, if you want to show how amazing or plainly different the Special World will be, the reader/viewer needs to know the comparable side, too.
In Star Wars, we find out that the empire rules the galaxy and the Jedi’s disappeared, while Luke is wasting his life. In E.T. we find out that Elliot’s father has left and the family struggles to cope with it. At the same time, E.T. was left behind by his family and is searched for by the government. Here you see that the “hero” can be anything, in this case even two characters at the same time.
