The film was originally released with the title "Star Wars".[22] The subtitles Episode IV and A New Hope were added starting with the film's theatrical re-release on April 10, 1981.[8][22] Star Wars was re-released theatrically in 1978, 1979, 1981, 1982.[98] After ILM used computer-generated effects for Steven Spielberg's 1993 film Jurassic Park, Lucas concluded that digital technology had caught up to his original vision for Star Wars.[11] For the film's 20th anniversary in 1997, Star Wars was digitally remastered and re-released to movie theaters, along with The Empire Strikes Back and Return of the Jedi, under the campaign title Star Wars Trilogy: Special Edition. This version of the film runs 124 minutes. The Special Edition contains visual shots and scenes that were unachievable in the original release due to financial, technological, and time constraints; one such scene involves a meeting between Han Solo and Jabba the Hutt.[11] The process of creating the new visual effects for Star Wars is featured in the Academy Award-nominated IMAX documentary film, Special Effects: Anything Can Happen, directed by Star Wars sound designer, Ben Burtt.[99] Although most changes are minor or cosmetic in nature, many fans and critics believe that Lucas degraded the film with the additions.[100][101][102][103] A particularly controversial change in which a bounty hunter named Greedo shoots first when confronting Han Solo has inspired T-shirts brandishing the phrase "Han Shot First".[104][105][106] Star Wars required extensive recovery of misplaced footage and restoration of the whole, before Lucas's Special Edition modifications could be attempted. It was discovered that in addition to the negative motion picture stocks commonly used on feature films, Lucas had also used internegative film, a reversal stock which deteriorated faster than negative stocks did. This meant that the entire printing negative had to be disassembled, and the CRI (color reversal internegative) portions cleaned separately from the negative portions. Once the cleaning was complete, the film was scanned into the computer for restoration. In many cases, entire scenes had to be reconstructed from their individual elements. Fortunately, digital compositing technology allowed them to correct for problems such as alignment of mattes, "blue-spill", and so forth.[107] Though the original Star Wars was selected by the National Film Registry of the United States Library of Congress in 1989,[108] it is unclear whether a copy of the 1977 theatrical sequence or the 1997 Special Edition has been archived by the NFR, or indeed if any copy has been provided by Lucasfilm and accepted by the Registry.[109][110] While the agency has a mandate to register films for preservation, it has no authority to secure its selections from authors or copyright holders.[111] From Wikipedia - https://en.wikipedia.org/wiki/Star_Wa...
