The MET is doing a new production of Parsifal next season, and I think you can count on it being one of the productions broadcast to movie theatres world-wide. The telecast should be on March 2, 2013 at 12 noon eastern time. Like most of Gelb’s productions, it sounds like it will have nothing to do with what the composer intended, but for $22 or so, you can always close your eyes.
There was a film version of Parsifal made in the early 80s by a German director that was very contrivertial because of the references to Hitler and the nazis. But it was an amazing dvd I had. Now can’t find it anywhere.
