Death Star
Although details, such as the superlaser's location, shifted between different concept models during production of "Star Wars", the notion of the Death Star being a large, spherical space station over 100 kilometers in diameter was consistent in all of them. George Lucas gave the original task of designing a "Death Star" to concept artist and spaceship modeler Colin Cantwell, who had collaborated with Stanley Kubrick on the 1968 film "". In a 2016 interview, Cantwell related that "I didn't originally plan for the Death Star to have a trench, but when I was working with the mold, I noticed the two halves had shrunk at the point where they met across the middle." As it "would have taken a week of work just to fill and sand and refill this depression," Cantwell suggested a trench to Lucas to save the labor. Lucas liked the idea, and the Death Star model was created by John Stears. The buzzing sound counting down to the Death Star firing its superlaser comes from the "Flash Gordon" serials. Portraying an incomplete yet powerful space station posed a problem for Industrial Light & Magic's modelmakers for "Return of the Jedi". Only the front side of the 137-centimeter model was completed, and the image was flipped horizontally for the final film. Both Death Stars were depicted by a combination of complete and sectional models and matte paintings.
Nien Nunb
With Nunb and Calrissian in the cockpit of the Millennium Falcon leading the attack, the Alliance Fleet arrived over Endor to find that the shield generator was still active, quickly realizing that the battle was a trap set by the Emperor, Darth Sidious, to engage and destroy the Rebel Alliance once and for all. The fleet remained over Endor and engaged Imperial forces in the hopes that Solo and his team would still be able to complete their mission and destroy the generator. The fleet kept to fighting TIE/LN starfighters and Star Destroyers, particularly once they learned that the Death Star was operational, after previously believing that it did not yet have the use of its primary, planet-destroying superlaser. Once Solo's team destroyed the shield generator, the Millennium Falcon entered the Death Star's superstructure and fired the shot that began a chain reaction that led to the battle station's destruction. Calrissian and Nunb were in a race against time as they outran the fireball that their attack created, and they escaped the Death Star just before it was consumed in a massive explosion. The Alliance was victorious, the Emperor was dead, and the Empire was shattered. Nunb joined his fellow Rebels on the surface of Endor where the Rebels held a celebration along with the native Ewoks, who helped Solo's team destroy the shield outpost.
