Other differences are that, after 1982, the only version to exist of this print is a 70 millimeter blow-up, in six-track Dolby Stereo. In 1990 and 1991, some Landmark theaters in the Los Angeles area played this version as an anamorphic, 35 millimeter reduction print from the 70 millimeter blow-up. The print was reported to be of poor quality: grainy, non-color-corrected, and with "wobbly", hastily cut-in end credits (which also showed up in the " Director’s Cut"). A new, final credit was added to the 35 millimeter reduction:

OK, so it was a 1982 print, and it did start to surface and they decided to make a D cut of the movie. Heres the question to this new finding....
Are they trying to say that the 70mm print was played as a 35mm print in the theatres? And if thats the case, how did they accomplish this? Because seeing a 70mm print when you normally see 35mm prints, you would say to yourself.....somethings a miss here
