This reminds me of materials received while I was working at a 14 screen theatre while putting myself through law school. Brother Bear came with documentation with respect to its changing aspect ratios (starts out 1.85:1, then expands to 2.39:1 within a scope frame), Some Kind of Monster (1.37:1 in a 1.85:1 frame) and Star Wars Episode III: Revenge of the Sith (volume setting of 7.0). Personally, I really appreciated it when distributors would go to this kind of effort.
