  "A wireframe, as you probably know, describes the contents of a web page by illustrating a mock layout. Usually wireframes are rendered in some kind of drawing program, like Visio or Illustrator, but can also appear as bitmaps or even HTML.

This step in both the movie making and web design process saves time and money, and allows the designer/director to adjust the big picture before moving onto the next stage where large-scale changes become much more costly.
