Seven different versions of Blade Runner have been shown, either to test audiences or theatrically. The best known are the Workprint, the Theatrical Cut, the International Cut, the Director's Cut and the Final Cut. These five versions are included in both the 2007 5-disc Ultimate Collectors Edition and 2012 30th Anniversary Collector's Edition releases. In the 2007 documentary Dangerous Days: The Making of Blade Runner, there is a reference to director Ridley Scott presenting a nearly four-hour-long "early cut" that was shown only to studio personnel.
