The Widescreen Museum has up some new material - an article about the remodeling of New York's Rivoli Theater in 1955 when it was reconfigured for showing films in the Todd-AO format. They did extensive remodeling to the interior, including custom made carpets and a concession stand for balcony patrons. They even had a $15,000 custom made curtain for the screen that was themed as the main, long-running attraction at the time, "Oklahoma".
It's no wonder I'm just not interested in going out to the movies anymore.
