Blade Runner (1982), Dir. Ridley Scott.
This film is a neo-noir. Some other notable neo-noirs are Pulp Fiction (1994), China Town (1974), and Old Boy (2003).
“Neo-noir (English: New-black; from the Greek neo, new; and the French noir, black) is a style often seen in modern motion pictures and other forms that prominently utilize elements of film noir, but with updated themes, content, style, visual elements or media that were absent in films noir of the 1940s and 1950s.” - http://en.wikipedia.org/wiki/Neo-noir
If you decide to watch this film you will find there are many different releases, and if you would like a recommendation, I highly recommend the Director’s Cut.
My favourite. Since forever.
