If you see the movie, you can see that we moved the Barber's chair from one side of the room to the other and down stage ... it took 3 seconds.
This strategy to developing a set is invaluable. DO IT. Require that your set company provide this and also take lots of pics with props in different locations, with and without people and even different lighting -- overhead, from stage right or left and straight on. It works. As you can see, the scale of the set model is small and allows for very easy modifications.
This is a scale model of the set, designed to allow us to see what the drawings look like in 3-D. It facilitates a clearer vision of the vision. It accomplishes many savings going forward:
determining distance between set pieces
loosely blocking movement on set
creating zones for furnishings, cast, crew, lights, cameras, etc.
placement of set pieces -- moving a sofa takes only seconds
allows us to see how master lights effect the set
where additional movable walls could be placed
This is the phase after the drawings are approved and certain set furnishings determined. As a blank whitepalette, it is so much more easy to scan issues and make decisions without the distraction of exact color, exact styling of set pieces and distances. The foam set helps bring the set to life in ways that get us to the next level ... the build.
