NEW YORK (AP) — "Mockingjay, Part 1" didn't catch fire like the previous installments of "The Hunger Games," but it still had the biggest opening of the year with $123 million at the weekend box office, according to studio estimates Sunday. Lionsgate's "Mockingjay" opened well below the $158 million debut of last year's "Hunger Games: Catching Fire" and the $153 million opening of the 2012 original.
