<P> As an in - joke, the film's working title was Jar Jar's Big Adventure, a sarcastic reference to the negative fan response to the Episode I character . </P> <P> In writing The Empire Strikes Back, Lucas initially decided that Lando Calrissian was a clone and came from a planet of clones which caused the "Clone Wars" mentioned by Obi - Wan Kenobi in A New Hope; he later came up with an alternate concept of an army of clone shocktroopers from a remote planet which were used by the Republic as an army in the war that followed . </P> <P> Principal photography occurred between June 26, 2000 and September 20, 2000 at Fox Studios Australia in Sydney . Location shooting took place in the Tunisian desert, at the Plaza de España in Seville, London, China, Vancouver, San Diego, and Italy (Villa del Balbianello on Lake Como, and in the former royal Palace of Caserta). At his own personal request, Samuel L. Jackson's character Mace Windu received a lightsaber that emitted an amethyst glow, as opposed to traditional blue and green for "good guys" and red for "bad guys". Reshoots were performed in March 2001 . During this time, a new action sequence was developed featuring the droid factory after Lucas had decided that the film lacked a quick enough pace in the corresponding time - frame . The sequence's previsualization was rushed, and the live - action footage was shot within four and a half hours . Because of Lucas' method of creating shots through various departments and sources that are sometimes miles and years apart from each other, Attack of the Clones became the first film ever to be produced through what Rick McCallum called "virtual filmmaking". </P> <P> Like The Phantom Menace, Attack of the Clones furthered technological development, effectively moving Hollywood into the "digital age" with the use of the HDW - F900, developed by Sony and Panavision, a digital camera using an HD digital 24 - frame system . This spawned controversy over the benefits and disadvantages of digital cinematography that continues as more filmmakers "convert" to digital filmmaking while many filmmakers oppose it . In contrast to previous installments, for which scenes were shot in the Tunisian desert in temperatures up to 125 ° F (51 ° C), the camera would still run without complications . Lucas had stated that he wished to film The Phantom Menace on this format but Sony was unable to build the cameras quickly enough . In 2002, Attack of the Clones became the third film to be released that was shot entirely on a 24p digital camera (preceded by 2001's Jackpot and Vidocq). The cameras record in the 16: 9 HDCAM format (1080p), although the image was cropped to a 2.40: 1 widescreen ratio . The area above and below the 2.40 extraction area was available for Lucas to reframe the picture as necessary in post-production . Despite Lucas' efforts to persuade movie theaters to switch to digital projectors for viewing of Episode II, few theaters did . </P>
