could get compex but old movies used to use some form of rolled up back
drop they could reel out when they had say a car that was stationary but wanted it to seem as if that car was moving by way of changing background.
IF you have a fly
system, perhaps doing some form of ceiling panel covering the entire
stage hung from it that is adjustable if not at times uniformly overly low and otherwise changing might be fun. This as with movable scenery panels to simulate walls which could move from place to place to simulate walls or hallways in a scene by scene type of thing, much less start moving in for a
effect, or allow for spears to come in from between them
etc. Given darkeness, shadows and large blocks making up the walls, it should be easy enough to get away without seemless walls or large gaps between scenery.
I would think some form of narrow passages and short ceilings would be fairly accurate - this given for the
stage it might need to be more of angles leading to narrow upstage parts out of visibility from the audience requirements. Still if the upstage is narrow and grows very sort and even narrow, one might get the idea even if the
down stage area is wider. See single
point perspective designs of Renaissance scene design for opera.
Could even make a ceiling that gets to be really short the further you go
up stage and not move it at all in not having a fly
system or not really wanting to move it. Some over bearing and seemingly weighty ceiling panel might add to the danger
effect, much less size and deep inside the pyramid type of atmosphere.
Wouldn't even need to match moving walls to the angle of the ceiling persay as long as the ceiling and floor made one large plane of blocks. Little dark spots by way of walls not matching the angle or exact height than could be a
stage convention in not matching up. Gaps between walls, not matching the angle, as long as they are panels and painted as if blocks, and what's in the background is black, the audience will connect the panels together as long as the acting is sufficient that they don't otherwise have time to look at the scenery because they are board with the show. This in
portable castered wall panels would also be a slightly less realistic design choice that's perfectly acceptable.
Rake the
stage also for some fun in running up and
down stage and even if really bold match that of the intrusive ceiling. Your actors will curse you than get to love running up and
down stage with the action. There is certain maximums you will need to work with in a
rake but the steeper the better if doing a lot of running about and fast action. Much les a short depth to the
stage.
Given scene changes I would force some similarity of location by way of a ceiling that is opressive in angle most overall.
Anyway, it's a unifying scenery
element to the location as an idea where than you could do the walls to change location within the area.
Study into ceiling panels will show how to do them and allow for top lighting.
That's my inital design thought or picture were I designing the show by way of concept given. Granted I would read the script a lot and be very prepaired to
throw out the initial design concept, but would otherwise if it seems to fit for a concept even if intial, look into it some.
