Star Wars nearly wasn't made. George Lucas submitted it to every movie studio and every movie studio rejected it except one. 2oth Century Fox was the only studio who accepted it.
The same thing also happened about the Star Wars action figures. No toy manufacturer would make the action figures except Kenner. But when they decided to start having the new Star Wars action figures made, every toy manufacturer wanted to make them. Kenner once again got to make them.
If 20th Century Fox had also rejected Star Wars, there would be no Darth Vader. No Luke Skywalker. No Princess Leia. Sci-fi fans all over the world would be less happy if Star Wars didn't exist.
