Well first lighting is a major consideration. It's the dark side of the moon, it's named so for a reason; it's dark.
Now I think it'd be cool is all the light came from moon bulbs, and torches, with a little ambient light, not too hard to set up but can you imagine the risk assessment?
Now what you want is looming figurines, (again risk assessment would be murder (Risk: Eye Poking)) something to really portray the evil of the Nazi party.
Even cooler, a big moon ship tilted about 25 degrees from horizontal towards the entrance of the room, lit up with high intensity, highly focused spot lights, stand out against the dark.
Maybe have ambient parade ground sounds in the background ("Achtung!").
Those are my ideas.
