Generally 16:9 isn't used by CFT Group either but there's no oposition to it. The rule with us is to make the film as the story demands so it could be 4:3, 16:9, CinemaScope or Super Panascreen-3:1 (which uses the 16:9 plate anamorphically), whichever best tells the story.
I personally have always loved the Cinemascope.
In sound I wonder if they don't use stereo. We will use anything from mono right thru to surround. Colour, monchrome, duotine?
At CFT the rules of film making are:
Rule 1) Use whatever it lawfully takes.
Now that we've covered the rules, let make movies and boycott 4:3-only clubs!

I wonder at you guys having formating problems. None of our films are formatted to 16:9 on the disc. Instead the film is anamorphically corrected into a 4:3 frame for viewing type at the editing stage. If the film is to be viewed thru equipment set for 16:9 the film is flattened slightly if Cinemasope or squeezed slightly if 4:3 and 16:9 is left full frame. The net result is that everything hits the screen the right way (apart from the Cinemascope stuff coz 16:9 isn't the correct width). If the disc isn't telling the equipment what format, then the equipment auto plays to fill the screen.
If we are presenting mixed programmes in a cinema everything will be fully anamorphic except where the films is stricktly 4:3 or 16:9. As far as the disc coding is concerned, everything is 4:3.
If the venue was stricktly 4:3 we wouldn't be interested in showing anything there. Bringing one's own screen is fine so long as it's bigger than what the venue has!
