In March 1976, George Lucas and his crew, who completed the preparatory work, began filming in Tunisia, North Africa. The entire filming work seemed to be a disaster at the time. In addition to the common dysentery caused by the crew, the set-up location was destroyed by storms several times, and during the filming, Tunisia also experienced a torrential rain that occurred once in decades. The filming process, which was originally a serious overrun and overdue, was continuously delayed by various unexpected natural and man-made disasters. Everyone wondered whether the filming could be completed on schedule.
After the film was transferred to a British studio, the shooting progress continued to be delayed. The shooting schedule of "Star Wars" has been seriously delayed, and ILM Industrial Light and Magic Special Effects Company is also having problems with film special effects. Because the special effects required by "Star Wars" were beyond the times at the time, ILM started almost from scratch. As a result, ILM had already spent half of the funds to make a few special effects shots until the filming was completed. All this makes George Lucas face increasing pressure.
As a representative symbol of the "Star Wars" movie, although the lightsaber in the film looks full of high-tech feelings, in the actual shooting, the actor only holds a wooden stick in his hand, and it is wrapped around the high for the movie screen. Reflective tape. In this way, the stick looks like a glowing light stick during shooting. In the later part of the paragraph, ILM made improvements to the lightsaber, using post-tracking technology to add light to the lightsaber. However, the lightsaber in the film is limited to the technical conditions at the time, and can not show the changes from scratch during the switching process of the lightsaber, so most of the lightsaber shots in this aspect of the film are realized by post-editing. In the passage where Luke learned to use the lightsaber on the spacecraft, this process of change from being to nothing was realized by stopping and shooting again. The lightsaber in the film still makes a buzzing sound when it dances. This sound is the sound engineer who has tried a lot of natural and unnatural sound effects and finally found the best way-to use a power-on during the post-dubbing When the brass tube dances in front of the speaker, the speaker will make such a sound.
