Lucas hired 'the Dean of Special Effects' John Stears

All six films of the Star Wars series were shot in an aspect ratio of 2.40:1. The original trilogy was shot with anamorphic lenses. Episodes IV and V were shot in Panavision, while Episode VI was shot in Joe Dunton Camera (JDC) scope. Episode I was shot with Hawk anamorphic lenses on Arriflex cameras, and Episodes II and III were shot with Sony's CineAlta high-definition digital cameras.[24]

Lucas hired Ben Burtt to oversee the sound effects on A New Hope. Burtt's accomplishment was such that the Academy of Motion Picture Arts and Sciences presented him with a Special Achievement Award because it had no award at the time for the work he had done.[25] Lucasfilm developed the THX sound reproduction standard for Return of the Jedi.[26] John Williams composed the scores for all six films. Lucas' design for Star Wars involved a grand musical sound, with leitmotifs for different characters and important concepts. Williams' Star Wars title theme has become one of the most famous and well-known musical compositions in modern music history.[27]

Lucas hired 'the Dean of Special Effects' John Stears, who created R2-D2, Luke Skywalker's Landspeeder, the Jedi Knights' lightsabers, and the Death Star.[28][29] The technical lightsaber choreography for the original trilogy was developed by leading filmmaking sword-master Bob Anderson. Anderson trained actor Mark Hamill (Luke Skywalker) and performed all the sword stunts as Darth Vader during the lightsaber duels in The Empire Strikes Back and Return of the Jedi, wearing Vader's costume. Anderson's role in the original Star Wars trilogy was highlighted in the film Reclaiming the Blade, where he shares his experiences as the fight choreographer developing the lightsaber techniques for the movies
