In which country did filming start for the original "Star Wars" film?

"Star Wars" (also known as "Star Wars: Episode IV – A New Hope") is a 1977 American epic space-opera film written and directed by George Lucas. It stars Mark Hamill, Harrison Ford, Carrie Fisher, Peter Cushing, Alec Guinness, David Prowse, James Earl Jones, Anthony Daniels, Kenny Baker, and Peter Mayhew. It is the first installment of the original Star Wars trilogy, and was retroactively made the fourth episode in the nine-part 'Skywalker saga' (albeit being the first released).

When principal photography began on March 22, 1976, in the Tunisian desert for the scenes on Tatooine, the project faced several problems. Lucas fell behind schedule in the first week of shooting due to malfunctioning props and electronic breakdowns. Moreover, a rare Tunisian rainstorm struck the country, which further disrupted filming. Taylor said, "you couldn't really see where the land ended and the sky began. It was all a gray mess, and the robots were just a blur." Given this situation, Lucas requested for heavy filtration, which Taylor rejected, who said: "I thought the look of the film should be absolutely clean... But George saw it differently, so we tried using nets and other diffusion. He asked to set up one shot on the robots with a 300mm, and the sand and sky just mushed together. I told him it wouldn't work, but he said that was the way he wanted to do the entire film, all diffused." This difference was later settled by 20th Century Fox executives, who backed Taylor's suggestion.
