I think it's good to re-say it from time to time:
- Original TV shows, especially from the 60's on, shot on 35mm, were "zoomboxed" from the original negative to produce 16mm 4/3 masters, (seen The Avengers post in this thread for explication). The image was thus, formated to fit the old tube TV screens. That's not "OAR" like a film shown in a cinema would be, that"s TVAR ie adjusted for tube TV.
- The set ups, as any filmmaker can see, (ie the way the actors are placed in the frame) are similar to widescreen 1.66 or 1.75 set ups, and this is especially true of TV shows in the UK which were shot by filmmakers who, for the last 10 to 15 years, had all been working in widescreen (as 1.37:1 basically died in the summer of 1953).
- scans of 35mm negs unzoomed shows insane amount of vertical space, top and bottom. Usually, like say Space 1999, the new 4/3 masters are zoomed on all four sides in because it doesn't look right presented the whole frame as shot.
- As shown in the Avengers demonstration in the first pages here, adjusting to 1.77:1 by using the complete left to right information, in most cases produces the exact, intended to be seen top and bottom information, while adding to the sides giving breathing space to the photography and sets.
- Irwin Allen productions were, for the most of them, shot in a way that allowed theatrical presentations, and in widescreen (see CITY BENEATH THE SEA comparison page 1).
- Basically, those series were shot to allow any kind of presentation, be it widescreen in the theaters for foreign releases, or cropped for TV.
I understand that, having seen those series for years cropped, viewers ask for a reproduction of that same experience on DVD or Blu, but TV have morphed over the years and is now widescreen 1.78:1. It's a reality, as this thread attest, that most shows will be adjusted for widescreen as the years go on (this is just the beginning), because it's also a matter of shelf life ie with TV screens now 1.78:1, you can't expect any show with a small fanbase to go on on cable reruns for new generations, if it doesn't look at least a bit current in it's presentation (hence, HD, widescreen).
Of course, this doesn't have anything to do with cropping top and bottom of already cropped 4/3 masters (see Kung Fu). It's about going back to the negatives, and adjusting for current TVs Aspect Ratio.
Regarding 2.35, those shows weren't shot in a way that allows for such reformating. The most you can do is 1.78:1 to 1.85:1 because that's how they were shot. Essentialy, their format was flexible within this boundaries and essentially (take the 4/3 versions of La Femme Nikita show, for that matter), one can see that the 4/3 presentations feel cropped, especially on a widescreen TV where you have black bars on the sides.
