With the dust settled in China, opening box office figures for “Looper” officially came in much lower than previously estimated: Pic tallied $16.7 million from Sept. 28-Oct. 7, with $4.2 million earned during the first three days.The film’s producers, Endgame Entertainment and Chinese company DMG, which is distributing “Looper” locally, first reported last weekend that the pic ranked No. 1 at the Chinese B.O. with an estimated $24 million. The official Chinese gross was delayed due to the country’s observance of a weeklong holiday that ended Tuesday. What caused the pic’s near-$20 million three-day discrepancy in China? Well, it’s likely that the originally reported figure wasn’t converted from local currency to U.S. dollars. For instance, 24 million yuan — the figure reported in U.S. dollars for “Looper” in three days — converts to roughly $3.8 million. Regardless, the pic’s producers aren’t too upset over the potential mix-up: “Looper,” which cost about $30 million to produce, has cumed $86.2 million worldwide, including almost $46 million Stateside (via Sony-TriStar). Beyond the mainland, “Looper” has done well in markets including the U.K., where it’s grossed $8.8 million; Australia ($7 million); and Russia, which so far has contributed $6.4 million (excluding this past weekend’s figures not available Wednesday). “Looper” expands today through Sunday into 14 additional overseas markets, including Argentina, India, Mexico, South Korea and Taiwan.
