The current correct ratio for 'scope is 2.39. It has changed over the years, but was 2.35 from (I think) about 1965 to 1985, so there are still people and documentation that say or print that.The offical size is now 0.825" x 0.690" which (2X) comes to 2.39130....... I think someone did a "SMPTE standard" history of it, showing what sizes 'scope has been over the last 50 years, but I can't remember where it was. More dead brain cells.... I'm guessing, but I wonder if 2.39 came into use after Lucas did his TAP survey in 1983 for "Empire." (If you never heard if this..) Just before "Empire" was released, Lucas created the TAP program to make sure just about every theater running that film was techinally up to par. For that one film, TAP sent a guy to your theater to not only check it out, but to file plates, push projectors, EQ sound.. whatever it took to get the best sound and picture out of your existing equipment. They also recorded data like screen height, width, and brightness, throw, lens sizes, aperture openings, projector angle, amp wattages, processor type, etc. There were even some reports that (for 70mm runs) if they found a bad speaker or something else wrong, it had to be fixed. If your theater didn't fix it, "NO 70 FOR YOU!" Anyway, I was talking to a guy at TAP shortly after, and asked him if there was anything interesting that came out of the data they collected. He said a few things, but one thing was how just about every theater cropped the image left/right. A few years after that, the offical 'scope size went from 0.825" x 0.700" to what it is now. I asked if Lucas was going to release all the data they took. I, personally, would find it would be very interesting to see. But the fellow said they would not be releasing it.

John:Some time ago, I provided a chronology of the changes to the projected image area for the anamorphic "scope" format to Martin Hart, Curator of the on-line "American WideScreen Museum". Here is a link to the data: http://www.simplecom.net/widefilm/widescreen/apertures.htm The current area is documented in standard ANSI/SMPTE 195 "Motion-Picture Prints --- Projectable Image Area": 0.825 X 0.690 inches (20.96 X 17.53 mm). In 1993, the image width was reduced from 0.838 to 0.825 inches to be consistent with the non-anamorphic "Style A" image width, and to reduce the risk of seeing the DTS time code at the left hand edge. The image height was reduced from 0.715 to 0.700 to 0.690 inches to reduce the visibility ("flash") of splices in the negative if the film was conformed as a single roll for printing. ------------------ John P.

John,Not "all" nude scenes are "covered up". I recall seeing the flick "Powder" at a theater where it was framed high. I even complained twice during the trailers to the management about it. Needless to say, towards the end there is a scene where some bullies rip Powder's clothes off and guess what was right there waving to the audience? The manager got a nice bitch after the film was over out by a mother who had brought her kids to this PG film for having such nudity in it. He could've avoided that if he had've just framed the thing during the trailers like I asked.  Another such instance happened on the video transfer of "Some Girls". Patrick Dempsey had a nude scene and the video transfer was done full frame. I think he prosecuted the company for it. That'll teach them actors to participate in non-scope movies! Long live scope!!!

There actually was once a proposal for a 35mm print format that printed 2-perf high frames "heads-to-tails", and then interleaved another set "tails to heads", with appropriate analog soundtracks on each side of the print. So the roll was projected in a normal 4-perf pulldown projector, first in one direction (heads-to-tails) and then the other (tails-to-heads) without rewinding. I recall that the projected image area was only about 0.700 X 0.350 inches. It might have worked as a budget format for reel-to-reel projection with changeovers, but there'd be no real advantage for platter systems. And the image area was barely larger than a 16mm print, so image quality would suffer.------------------ John P.
