Luis, I agree with you about packaging... it can be an artform in itself and adds to the collectible value of a disc, not to mention how it can be one of the things that keeps digital downloads from completely taking over the market sooner than it already will. I still believe in packaged media over downloads because I still like the feel of actually having a physical object in my possession, rather than something I can erase with a magnet or an accidental push of a button. Reckon that makes me an old-timer... ;-)
Fritz, there are several reasons why special features might get broken up for no apparent useful purpose. One you already mentioned: by breaking them down into smaller pieces, they may be considered "promotional" rather than straight content, and as such might be exempt from royalties that might otherwise be due to the performers. SAG rules allow exceptions for "promotional" use of footage without residuals, since contracts allow (or demand) that material of the performer be made available to promote the film, which then generates revenue. This was a sticky point for many years... I remember back in the early 90s when I wasn't allowed to put the trailer for a movie on the same disc as the movie itself without signed waivers from all of the actors because SAG said including a trailer did not qualify as promotional if you had to buy the disc to get it.
Another reason to split up a feature into smaller pieces is to get around subtitling policies to save money. Some territories or studios require any feature longer than 30 minutes to be subtitled in all languages, which costs money, so by breaking it down into smaller chunks, the studio may save the cost of creating and including subtitles. This is generally a stupid reason and may not be done as much any more; most things get subtitled anyway these days (or should be).
The final reason is simply for marketing purposes: it looks better on the packaging to say "ten featurettes on the making of the film!" rather than "one big documentary!" More bullet points means more perceived value.
Brian, if the film was originally composed for 2.35 in Super-35, then the primary preferred composition would be 2.35, but the P&S version would have the chance of at least not sucking because there would be more picture available in the Super-35 area outside of the 2.35 composition to work with when recomposing for 1.33. In my experience on The Abyss, T2 and True Lies (and even Titanic), the films were never composed for or preferred in 1.33 composition except as a compromise for NTSC. Unless these films were originally composed for 1.33 and simultaneously protected for 2.35, I don't really see JC preferring 1.33 over his original composition. So I don't see any truth in that... but for all I know, JC might claim it to be true just to stir things up... ;-)
As far as I know, Avatar was composed for 1.78 HD for better stereoscopic 3D but protected for 2.35 for 2D widescreen, whereas all of his previous films were composed for 2.35 but only semi-protected for minimally 2.20 (70mm) and maybe to 1.85 at most. If there was more image available beyond to 1.33, that was fine, but the 1.33 full image was never protected to be fully used on any of his previous films. Aliens was shot Academy aperture and hardmatted at 1.66 (since it was shot in England) but composed for 1.85 (which is why footsteps would be out of sync if you saw the first few PowerLoader shots in the original 1.66, as I did when doing a transfer back in 1990). T1 was composed for 1.85 but exposed to the full standard Academy aperture on the film.
Hope this explains,
