Several years ago I saw Spielberg's AI in a second run showing at some small and old theater in, I think, Redford Michigan. Skip Rosenthal played banjo before the picture. The straight-back seats were utter agony to sit in for 2+ hours.
I think I posted on this subject some time ago - if I'm repeating myself I apologize.
As the movie ran, the bottom of the overhead microphone could clearly be seen protuding down into the image in many of the scenes. So much for suspension of disbelief. I'd guess that the film should have been projected onto a different shaped screen - more rectangular - which would have clipped off the top portion of the screen containing the mike. AI on DVD is matted so as not to include the mike. What surprised me was that a release print of anything should contain the microphone. That almost seems to negate the concept of frame composition, if films as released contain the gaffer standing just at the edge of the frame - though you can't see him because he spilled off the edge of the projection screen. It seems that zoom back should let us see such things, though I've never found that to be the case.
A very strange occurance which I've never properly sorted out.
