Sony expects to dominate the worldwide box office this weekend as Roland Emmerich's latest disaster spectacle, "2012," opens across all territories, looking to match the mammoth foreign success of the helmer's "The Day After Tomorrow."

Domestically, "2012" debuts in 3,404 runs, and box office observers say it could open north of $40 million or even substantially more. Overseas, it opens on roughly 13,000 screens in 105 countries.
