While Warner Bros.’ “Wrath of the Titans” ($42.1 million) again conquered the overseas B.O. over the most recent sesh (April 6-8), Paramount and Fox Intl.’s 3D re-release of “Titanic” made waves in its opening frame, collecting $35.3 million from an expansive 84-country spread.“Titanic” 3D earned top marks in debut markets including the U.K. ($4.4 million) and Germany ($3.4 million), though China — where the pic debuted April 10 — shined brightest, contributing $11.6 million just from its opening day locally. Pic’s Chinese take was Fox’s biggest opening day there ever and the country’s second-biggest behind “Transformers: Dark of the Moon” at $15 million. Fox Intl. released “Titanic” internationally, while Par handled domestic rights. The 3D re-do’s stellar start in China was boosted by the pic’s Imax presentation, which contributed $1 million from only 64 theaters, for a per-screen average of $15,625. Pic played at a total approximately 2,400 3D screens in China. The film’s hearty start is impressive given its three-hour-plus runtime, which posed difficulties in securing screens — both domestically and abroad. What’s more, though “Titanic” cost $18 million to convert (at the high end of most conversions), with a late-breaking marketing spend, its worldwide cume of nearly $70 million through April 9 makes the 3D version highly profitable. Meanwhile, the ledger sheet was also looking good on Warners’ “Wrath,” budgeted at $125 million (not including marketing), comparable to the original. The sequel crossed the $200 million global mark in its second weekend. “Wrath” will bow in Japan on April 21; “Titanic” 3D expands into Latin America the weekend of April 13.
