'Rogue One' and 'Sing' take the top box office spots over the Christmas holiday

Call it moviegoers hungry for a sassy robot and some daring acts of galactic rebellion. For the second Christmas movie season in a row a "Star Wars" franchise film has dominated the holiday box office. Also for the second year in a row, North American ticket sales are projected to exceed $11 billion, according to the entertainment data firm ComScore. And as the year comes to a close, 2016 is expected to see a 1.5% increase in ticket sales over 2015 ($11.3 billion versus $11.1 billion). That puts the Gareth Edwards-directed action flick, set just before the events of George Lucas' 1970s trilogy, well above the Disney film's approximately $200-million production budget.
