Sculpting Mars at SAM: Day 9
The transformation of Polystyrene foam blocks into a Mars landscape requires vision, skill in sculpting, shooting concrete, and painting; and effective management—the first and last exemplified by Red Hen founder Danica Vallone who maintains a working relationship with some 250 individuals working in set design and construction. She and her team have brought to SAM the unique ability to transform two dimensional drawings and photographs into three dimensions, demonstrating a deep understanding of form, texture, and color and the physical tools used to employ them.
The sculpting crew (as noted in prior blog entries) hold what is perhaps the most challenging of the processes—starting with raw materials and making those first cuts into the massive blocks of foam with a vision toward the end product. This process is principally one of subtracting material, cutting into square blocks to remove large and then increasingly smaller pieces using hot wire knives, chain saws, horse brushes, and an assembly of home-built hand and power tools. Foam is added too, building beyond the otherwise imposed limit of a wall or corner, as with the rockfall in the southeast corner of the SAM Mars yard.
With the shapes established, the plaster crew covers the foam with a thin layer of a custom blend of Poly-bond structural concrete, sand, and adhesives designed to bond to foam. This concrete is tinted to establish a base color such that the final, painter crew can work from that base color with less effort and material, as compared to starting from a standard concrete gray.
While Hollywood sets built from foam are typically covered with 1/8″ concrete, thicker for areas on which actors might walk, the SAM Mars yard is 1/4″ nominal with the west wall K-rock covered in expanded steel, steel mesh, and in some areas up to two inches hand-troweled concrete.
Three sculptors were at SAM for eight days, the four plasterers for less than two days (starting today), and as of this coming Sunday two painters will be at SAM for four days. Each crew brings to this project some of the finest talent in Hollywood, with individuals who have two or three generations in skill and experience in their respective trades. The quality of production against an impossible timeline has been truly awe inspiring and points directly to Red Hen’s ability to manage such a complex endeavor.

The blue color is a layer of “Weldcrete”, a kind of chemical adhesive that helps the Polybond-based shotcrete adhere to the foam.
