The Gold Box deal of the day today at Amazon is the Blade Runner Five-Disc Ultimate Collector’s Edition on limited edition DVD for only $37.49 (52% off the list price of $78.92) or on Blu-ray for only $18.99 (53% off the list price of $39.99).

The DVD version comes packaged in a limited edition individually numbered case that looks like Rick Deckard’s briefcase, complete with handle, and includes a lenticular motion film clip from the original feature, miniature origami unicorn figurine, miniature replica spinner car, collector’s photographs, and a signed personal letter from director Sir Ridley Scott.

Both DVD and Blu-ray sets contain five versions of the classic scifi film starring Harrison Ford, including the newest “Final Cut” version from director Ridley Scott; there’s also the 1982 theatrical and unrated international versions; the 1992 director’s cut without Deckard’s voiceover narration and “happy ending” finale and adds the unicorn” sequence; and the rare workprint version with altered opening scene and altered scenes, Deckard narration only in the final scenes, no “unicorn” sequence or “happy ending,” and alternate music.

Both 5-disc sets also come with tons of bonus material such as never-before-seen added/extended scenes, added lines, new and improved special effects, making of and behind-the-scenes featurettes, and director and filmmaker commentary. Disc 2 has the over 3-hour making-of documentary “Dangerous Days.”
