“The Hunger Games: Mockingjay – Part 1,” starring Jennifer Lawrence as the young archer who rallies the downtrodden citizens of a dystopian society, collected $21.6 million to lead the box office charts for a third consecutive weekend. DreamWorks Animation’s “Penguins of Madagascar” was second with $11.1 million at U.S. and Canadian theaters during a slow post-Thanksgiving weekend, when moviegoers traditionally turn their attention toward shopping. Lionsgate distributed the latest Hunger Games installment, while “The Penguins of Madagascar” was released by Fox, a unit of Twenty-First Century Fox.
