At an afterparty for a screening of Mamma Mia!, Pierce Brosnan consoled his co-star Amanda Seyfried and her anxiety about the film's opening. Seyfried was worried that nobody was going to watch their movie this weekend, because she assumed all movie goers would see The Dark Knight over and over again. Brosnan assured Seyfried that there'll be an audience for the film, taking time to explain to her about the concept of alternative programming. Brosnan said, "When The Dark Knight is sold out, which it's going to be, what else are people going to watch? That's where our movie comes in. We're going to be just fine, champ."
