The DreamWorks Animation sequel was powered by a strong debut in China, where the picture picked up $25.9 million. Though “Dragon 2’s” $171 million domestic gross was lower than expected and lagged behind its predecessor, it’s been a monster overseas. Its global gross now stands at $537.2 million, easily topping the $494.8 million made by the first film in the series.

Sliding in at number two, Marvel’s “Guardians of the Galaxy” padded its global grosses with $33.1 million in receipts from 65 territories. The space adventure debuted in more than a dozen new countries, including France, Spain, Belgium, Jordan and Kuwait. Its worldwide treasury now stands at $418.7 million.

The picture has earned $185.1 million globally, and debuted last weekend in Argentina and Brazil, where it made $1.1 million and $6 million, respectively.

In fourth place, “Lucy” gunned its way to $22 million from 28 territories, while “The Admiral: Roaring Currents” continued to shatter records in Korea, earning $20 million to capture the fifth spot.

“Roaring Currents” documents a historic naval battle and the sea adventure become the biggest film of all time at the South Korean box office this weekend, having become the  country’s first film to sell more than 14 million tickets  and to pass the $100 million mark.
