Star Wars as Pulp Sci-Fi
mikelove writes "Salon has an article arguing that Star Wars owes its origins to pulp science fiction and not Joseph Campbell-esque mythology. Finally SOMEONE is realizing this... Also makes the suggestion that Lucas/Kasdan didn't really write The Empire Strikes Back, which makes a certain amount of sense when you compare it to Lucas' other screenplays."
Do note that labeling it as "Episode IV" and the subtitle "A New Hope" both came well after the the film was released. Later prints had the title sequence changed accordingly, but IIRC only after _ESB_ came out labeled as "Episode V".
When all you have is a hammer, everything looks like a skull.
