The production designer is the "director's eye" according to famous PD Ken Adam. The production design team implements the script in visual terms, conceptualizes and orchestrates spaces, defines milieus, establishes color schemes for dramatic purposes and plays a central role in creating the atmosphere and fictional world of a film. Beyond such design-intensive genres as science fiction or the history film, convincing production design is also a central factor in productions less obviously concerned with scenery, the essential contribution it makes to the "art" of film being often overlooked despite it being literally impossible to miss.
