“The Hunger Games: Mockingjay – Part 1” claimed the top spot at the box office for the third weekend in a row with an estimated $21.6 million. “Mockingjay – Part 1” is still about $78 million shy of where the previous installment, “Catching Fire,” was in its third weekend just last year. In the specialty box office world, awards hopeful “Wild,” starring Reese Witherspoon, opened in 21 theaters Wednesday, earning an estimated $630,000 over the three-day.
