 In the video version of the original, when the stormtroopers are chasing Han  down the hall, you can hear one of them say "Open the blast door. Open the  blast door" as Han and Chewbacca pass through it and leave the troopers on  the other side. In the special edition, you can hear one of the stormtroopers  say "Close the blast door" before it closes. The scene is actually a little  funnier because its his own fault that the door closed. The extra dialogue  was "lost" on the home video release but the line did exists in earlier  theatrical versions, as evidenced by the 1977 audio recording of the film  entitled "The Story of Star Wars." This LP/audio cassette includes that line,  in the exact same voice and reading as it appears in the special edition.  Also note that foreign language versions of the film did have the translation  of that line. The "close the blast doors" line is also seen in a Star Wars  clip in the 1993 special "George Lucas: Heroes, Myth and Magic" on the PBS  series _"American Masters" (1983)_ (qv).
