It is unquestioned that the interior of Colonial One was directly influenced by the Pan Am “Orion” Space Clipper from the film “2001: A Space Odyssey.” Many of the preproduction reference photos used prior to filming of BSG’s 2003 Miniseries showcased publicity stills from the film “2001: A Space Odyssey.”
The following screen cap from the film “2001: A Space Odyssey”, showing the passenger compartment on the Orion, clearly illustrates the influence on the Colonial One’s interior.
The Colonial One’s interior design is highly influenced by the passenger compartment from the Pan Am “Orion” Space Clipper’s. As you can see in the following screen cap the seating area is recessed just like on the Pan Am “Orion” clipper’s passenger area along with hexagonal bulkheads, angled ceilings and diagonal lines on the bulkhead walls.
After the MiniSeries the Colonial One set was modified so that the floor was one level to accommodate ease of filming and also the updated decor of desks and larger furniture.
