Never mind 3d... can anyone confirm if the aspect ratio of this Blu-ray is correct? I've compared it to the DVD fullscreen release, and it looks like the widescreen is cropped from the fullscreen, rather than the reverse. There's quite a lot of material missing at top and bottom in the Blu-ray, but no extra material at the sides compared to the DVD. On the other hand, the credits are centered in the fullscreen version, suggesting maybe it was intended to be matted for widescreen. If so, which is definitive?
"Films shot with the All-Media rig were composed for the aspect ratio of 1.85:1." It was definitely shown originally as 1.85 both in 3d and 2d. Don't know if all-media was a matted format, or if it is just that we don't have correct copies of it on the blu-ray and DVD version.
DVDbeaver posts confirms that it was an open matte format. It was framed for 1.85 but they filmed to protect the academy ratio (4:3) so it could be shown in theaters which had not yet been converted to widescreen. Not sure if they were also thinking for TV, back then.
Thanks for the info. After seeing the 4:3 version several times, I'm very conscious of the missing material in the 1.85:1 copy. But as long as someone remotely connected with the original production made the decision, I'll be happy to respect it.
