British actress Geraldine Chaplin (78) encouraged young actors. When she was asked for advice for the audience as part of the “Berlinale Talents” program to promote young talent, she replied: “Stay on the ball.”

She learned this from her father Charlie Chaplin, who never gave up himself. “My dad was the only mentor I’ve ever had,” she said Tuesday night, “and he was pretty good.” Geraldine Chaplin plays a role in the film “Seneca” by Robert Schwentke, which is being shown at the Berlinale.
