The literati are pretty much guaranteed to appear for each summer's three productions at the Colorado Shakespeare Festival. And since professors often assign the shows to their students, you'll see lots of bright young people there as well. It all makes for a pleasant and congenial vibe in the lovely open-air Mary Rippon Theatre. But professors also go because these shows can open up new interpretations or illuminate a facet they think they know by heart. It's fun overhearing or joining their discussions at intermission — and just as much fun to listen when they take a poor production apart scene by scene.
