Meanwhile, the overseas box office was blanketed by a new Ice Age . The latest installment of the animated franchise, Continental Drift , earned $80.3 million in its opening weekend in 35 countries. The three previous entries also performed far more strongly abroad than they did domestically. Indeed, the third Ice Age movie grossed $690.1 million abroad -- three times what it earned domestically. Meanwhile, Sony dropped The Amazing Spider-Man into 13 foreign markets, mostly in Asia, where it nabbed $51.1 million. The movie is due to expand into most other major overseas markets next weekend.
