Jeff Cooper does a lot of dub stage work, though his book mainly deals with music studios.
JEFF COOPER ARCHITECTS
A technique that works quite well in re-recording theaters is what I have jokingly referred to as "wedgie walls" for years. Wedged walls work in other applications as well, but they are especially good in mid-sized to larger dub stages.
The beauty is that you can design them for so many things, from helping with geometry, to trapping, to diffusion. You can make slat traps, tuned perf traps, resonant diaphragmatic absorbers, traditional bass traps with 703-airspace-hangers, chunk traps, broadband traps, pure reflection, simple mid/high absorption, or any combination thereof. Just because they look the same from the outside doesn't mean they are all the same underneath. Use whatever combination you need to accomplish your design goals within the whole-room plan.
Here are a few examples in smaller to medium-sized rooms that I've designed:
Mastering studio in Los Angeles Mastering studio outside Boston Multiple use college studio
And here are some examples in larger dub stages (not mine):
