15 things we just learned about the making of 'Star Wars: The Force Awakens'

Now that "Star Wars: The Force Awakens" is out in theaters, a myriad of books and novelizations Disney has been heavily guarding to prevent spoilers have also been released.

Among those books is "The Art of Star Wars: The Force Awakens," a fantastic look at the concept art, drawings, and ideas that went into the production of the film as well as interviews from concept artists who worked on the movie.

I definitely recommend the book if you were a fan of the film.

While we still have a lot of questions after seeing the latest installment of "Star Wars," the book helps shed light on some of the early inspiration for "The Force Awakens."

Here are 15 things we learned while reading "The Art of Star Wars: The Force Awakens."

Warning: There are some spoilers ahead if you haven't seen the film.

Rey was originally called Kira.

Many concept images of Rey are labeled as Kira in the book. Screenwriter Michael Arndt ("Toy Story 3") described the character as a "loner, hothead, gear-head, badass."

Finn's character was named Sam and he was going to be rescued by aliens on Jakku.

After Poe and Finn crash land on Jakku early in the film, Finn — then known as Sam — was going to be rescued by an alien tribe and reborn a hero. Yeah, it sounds a bit out of place.

There were plans for a double-colored lightsaber.

Coproduction designer Rick Carter came up with the idea of a dual lightsaber that was red on one end and blue on the other.

"Early on, Rick was really keen on bringing this concept of fire and ice together visually. He suggested, because I had one lightsaber that was blue, 'Why don't we make it a double lightsaber?'" said concept artist Erik Tiemens.
