Looks like a dodgy aperture plate or the screen masking motor was giving up and projectionist didn't make any preparations to see that the masking was at correct 2.35:1.

Films often on video disc are seriously cropped on the sides and often sometimes the top and bottom of scope film. Someone needs to go to SpecSavers!

Mike Verta explained that the print had platter scratches on the edges, so the projectionist probably cropped close to hide them. Also, I think the Senator was a primarily 70mm venue, so its screen was closer to the 70mm aspect ratio, which isn't as wide as 2.35:1. The amount of image shown in the Senator screenshots has an aspect ratio close to 2.20:1.

But did the projectionist crop it too much, even if we take these things into account? Not sure, it sure looks like it though...
