The skies are always dark with airborne filth in this Los Angeles of the future. It usually rains. The infrastructure looks a lot like now, except older and more crowded, and with the addition of vast floating
zeppelins, individual flying cars, and
towering buildings of unimaginable size. When I first saw the film I was impressed by the giant billboards with moving, speaking faces on them, touting Coca-Cola and other products. Now I walk over to Millennium Park and see giant faces
looming above me, smiling, winking, and periodically spitting (but not Coke). As for the flying cars, these have been a staple of sci-fi magazine covers for decades, but remain wildly impractical and dangerous, unless locked into a control grid. - Roger Ebert on
Blade Runner
