Actress and model Dylan Penn, the daughter of Sean Penn and Robin Wright, joined her father on The Late Show with Stephen Colbert Thursday. And she described what it was like working together on the new film, Flag Day, which Sean directed and also stars alongside Dylan. And apparently she had no reservations about getting into some on-set battles with the boss. “We had one major, I think it was a two-hour standoff about a note that he had,” Dylan recalled. “About whether I could wear, or not wear, mascara.” And then Colbert asked if they took the matter into a private setting or laid it all out in front of the crew. And Dylan said it was all very public. “Once it was clear that she was making the wrong decision, I just went and sat down,” Sean added. “And then the silence was one the crew had to live with for two hours while the Penns figured it out.”
