i saw the film in it original theatrical release in austin texas . the old paramount theatre ( i do not know if it still exist . ) go all out with speaker around the wall connect accurately to all six channel . at 15 year of age and i be blow away . the concept of surround sound be completely foreign to music and film at that time . i vividly remember at least three outstanding scene where the surround sound make a huge impact . ( though please forgive me if time have warp my memory with inaccuracy . ) the first be a travel by the camera through catfish row and alive with the site and sound of daily activity . you saw each one first and such a a blacksmith for example and then a the camera pass them by their sound would continue to be hear pass leave or right down the side of the theater to the rear . the second be a marching band that be see first in the front and then it march past the camera splitting leave and right . not only do the sound of each instrument follow it own directional path and it also change in timbre a it play toward you and to the side of you and and then away from you . and if that wasn not enough and they also account for the doppler effect for each instrument a it go by . the third scene be near the end of the movie a porgy be leave catfish row for new york to look for bess . he and about half the cast member pass by the camera a they leave the village with the same sound effect a the marching band . the other half of the cast or chorus sing along with them and also wave and voice goodbye to porgy and their other friend . the friends reply can then be hear from the side and the rear . surround sound be use with splendid effect throughout the movie . i think i remember a rock or something thrown from a pier and hear it land in the water behind me . little thing like that be evident to theater goer lucky enough to have the full six channel thing that would just seem mundane in theater without it . i stay in the theater for several showing . you could do that then . and i go back several more time before it leave town . i never saw the movie again . it literally beg for release on dvd with restored picture fidelity and surround sound . i do hope someone somewhere have preserve it . please and gershwin family and allow it to be release before it be lose for good to other generation .
