At any rate, if I were to put the special features on the same disc as a movie, I would spread them across all discs. So the special features that pertain to the theatrical version (such as the 1977 ‘Making of Star Wars’ documentary) would go on disc 1, the features that pertain specifically to the special edition (such as “anatomy of a dewback”) would go on disc 2, and so on and so forth.

I’m not doing that, since I think it’s a lot simpler and cleaner to have all the special features together on their own disc, but if I were to do that, that’s what I’d do.
