There were many amazing moments at the Sundance Institute’s 25 Anniversary Gala in New York this evening — including a great piece of performance art by Miranda July — but the evening’s most unexpected surprise may have occurred during the pre-dinner cocktail party. The wait staff serving hors’ d’oeurves were all actors who were giving back to Sundance as they produced expressions of shock, amazement, and slight embarassment among the attendees. Parker Posey, Kathy Bates, and yes, Paul Newman were all game, circulating through the crowds in white shirts and black aprons, handing out the finger food to those who came out to hail Sundance on its silver anniversary.
