Production Design
Here is an excerpt taken from Wikipedia.
In film and television, a production designer (PD) is the person responsible for the overall visual look of the production. Production designers have a key creative role in the creation of motion pictures and television. Working directly with the director, cinematographer, and producer, they must select the settings and style to visually tell the story. The term production designer was coined by William Cameron Menzies while he was working on the film Gone with the Wind.[1] Previously (and often subsequently) the people with the same responsibilities were called art directors.[2] It is sometimes also described as scenic design or set design.
