LOCARNO, Switzerland — Susan Sarandon was feeling a bit feisty during her Variety master class Aug. 8 at the Locarno Intl. Film Festival, where she spoke about her career, acting technique and, of course, politics.“It seems absurd to say that an artist doesn’t have a right to be political when you elect a president or governor who was an actor — both very bad actors, by the way,” she said, seemingly referring to Ronald Reagan and Arnold Schwarzenegger. “Maybe the rule in the United States is that you can only be in politics if you’re a bad actor. That’s probably going to be on the AP right now and the one quote that gets everywhere from this,” she said. That evening, Sarandon was presented with a Locarno Excellence Award in the Piazza Grande.
