Stanley Kubrick is regarded by film critics and historians as one of the most influential directors of all time.
 Leading directors, including Martin Scorsese, Steven Spielberg, George Lucas, James Cameron, Woody Allen, Terry Gilliam, the Coen Brothers, Ridley Scott, Paul Thomas Anderson, Christopher Nolan, David Lynch, and George A. Romero, have cited Kubrick as a source of inspiration, and in the case of Spielberg, collaboration.
 In an interview for the "Eyes Wide Shut" DVD release, Steven Spielberg comments that "nobody could shoot a picture better in history", and that Kubrick told stories in a way "antithetical to the way we are accustomed to receiving stories".
 Writing in the introduction to a recent edition of Michel Ciment's "Kubrick", film director Martin Scorsese notes most of Kubrick's films were misunderstood and under-appreciated when first released, only to be considered masterpieces later on.
