The hero of the beloved Star Wars trilogy is Luke. The principle dynamic is the complicated relationship between Luke and his father. Not coincidentally, George Lucas' last name sounds a lot like Luke. That's the one he identified with. George Lucas had a tumultuous relationship with his own father, and people who know him say that you can't understand the backstory of the movies without knowing that his dad was occasionally difficult but also very loving. They had a big break between them. In those movies, he's very focused on sons and fathers.
