Um, okay, haha. OK, what to cover? Well, there’s the interesting shadows inside the lit superstructure. There are four long dark areas along the upper spine and more around the vertical sides at the rear of the stern, also what appear to be a couple of large angled pipes flanking the rear central viewing area or hangar or whatever it is. These are actually the model’s steel armature showing through the translucent covering.
The Disney art department blueprints demonstrate that the original plan for the mandibles and bow area was for the framing to be built around an internal lightbox, same as the rest of the ship. In the end only the part between the dock and the observatories was boxed in, at least on one of the two models. Just before the Palomino takes off, there’s a panning shot of the front of the ship – you can see right through the mandibles from front to rear. (Same deal at the beginning of the film, you can see through from the rear of the mandibles as the Palomino does its flyby.)
But there are behind-the-scenes shots (and probably some in the film, can’t recall) where the model appears to have structure inside the mandibles. My guess is that the first model followed the plans and they didn’t bother for the second one, but ended up shooting more with that model. (Most likely the two models were built at pretty much the same time, but perhaps that one was better overall for some reason?)
The bridge is shown in some of the early concept paintings as being tiltable. This was actually designed and built into the filming models - that’s what the big half-circle details right under the bridge are about. Originally they each connected to a couple of servomotor type housings sitting below them, and the four girder support struts didn’t exist. All changed at some late point; it’s possible some of the BTS photos were just taken at times when the four supports were temporarily removed but the servo housings were gone in the film so I think not. My guess is the concept was abandoned because the tower looked too spindly and needed visual beefing-up.
Did you know each main engine has a little catwalk all the way along the top of it, complete with a handrail and several sets of steps?
1979 saw the release of two films that are rare in science fiction in that both featured starships with well-realised interiors which *
actually fit inside their exteriors*: the USS Cygnus and the Nostromo.
Well, mostly, I'm not sure about the Nostromo's engine room.
The Cygnus main corridor, of silly asteroid notoriety, is simply the entire volume of the spine of the model. The walkways along the sides of the corridor are at the level of the bottoms of the side “modules”, as they should be, and the doors out to the side modules are in the right places. There are of course many FX flubs and/or compromises where things were changed around on the basis of ‘it’s only a movie’, but the concept and design work was unusually careful for the period.
The odd details under the side modules are interesting. Those concept paintings which appear to show the ship under construction, where modules are in flight as separate units – they’re actually in flight, as separate units! The domes under the modules are control bridges, and the four odd antenna-like things are actually folded landing gear. Each module is a separate lab/ship which can presumably fly off on its own research mission. They each have an airlock at the front and rear ends, connecting to the next module in sequence. Even the fuel tank modules have these airlocks, and walkways for EVA activity.
The models were actually designed with all this in mind, with each side module as a separate ‘wild’ unit which can be removed. Not sure they were built that way as well but it seems likely given details of some of the destruction shots.
The ship is 2352 feet long and the middle section is about 200’ wide and 50’ high at the modules. All the Disney drawings were dimensioned in ‘real-world’ units.
Will that do for now?
