Based on Philip K Dick's surrealist sci-fi novel, Do Androids Dream of Electric Sheep, Ridley Scott's masterful adaptation makes a belated but welcome DVD bow. Harrison Ford's voiceover has now gone, along with that tagged-on happy ending, which famously used up some of Kubrick's aerial outtakes from The Shining.
Despite its familiarity - having inspired every sci-fi dystopia from James Cameron's The Terminator to Spielberg's A.I. Artificial Intelligence - what continues to amaze is Blade Runner's inability to date; it may have been made when computers were the size of tenement blocks, but the stunning visualisation of a corroded near-future LA still steals the breath like no other.
