7. Luke’s green lightsaber in Return of the Jedi was initially blue.
Yes, Luke’s new lightsaber was going to be blue. In fact, the same was shown in early promos of Return of the Jedi. However, Lucas decided to change it to green exclusively on the grounds that the blue blade was hard to see amid the battle scene at the Sarlacc, as it was getting lost against the blue sky.
8. Lightsabers were illegal amid the Empire.
It wasn’t sufficient that Emperor Palpatine attempted to execute all the Jedi; he made owning a lightsaber a crime. Furthermore, he prohibited the exchange of the crystals expected to make lightsabers over the galaxy, regardless of what planet they developed on. News is, Darth Vader has unique dispensation to employ his lightsaber.
9. Lightsaber blades are animated since the original special effects were awful sucked.
The initial endeavor at lightsabers utilized long, reflective, three-sided rods. The rods were spun with engines inside the grips, which meant that the blades would consistently reflect the stage lights. This looked terrible. As a result, animation was included later on. It was then that Lucas chose the lightsaber blades should have colors. Initially, they were going to simply be white.
