BERLIN — Lionsgate has strengthened its international partnerships, expanding existing pacts with Studiocanal in Germany and Austria, and with Celestial Tiger Entertainment in all of East Asia.The multi-year deals are the latest steps in Lionsgate’s strategy of creating an international distribution network with leading partners in major territories. The agreement with Studiocanal extends the media giant’s distribution of “The Hunger Games” franchise in German-speaking territories to include the final installment of the series, the two-part “The Hunger Games: Mockingjay,” and also encompasses other films from the Lionsgate slate. The two companies announced in May that Studiocanal would distribute the franchise’s next installment, “The Hunger Games: Catching Fire,” as well as the renewal of Lionsgate’s distribution agreement for Studiocanal’s library of more than 2,000 titles in North America. “Studiocanal epitomizes the kind of blue-chip partner around whom we are building our international distribution network,” said Lionsgate Motion Picture Group co-chairs Patrick Wachsberger and Rob Friedman. The companies said the new agreement “complements Summit Entertainment’s continuing output deal with longtime German partner Tele Munchen.” Lionsgate acquired Summit in January, but the Lionsgate and Summit labels remain separate. Lionsgate and Studiocanal are also partnered in the Elevation Sales home entertainment joint venture in the U.K., as well as in the distribution of the Miramax library worldwide. The two companies likewise joined forces on the 2010 release of the hit horror film “The Last Exorcism.” Lionsgate also boosted its exclusive partnership in Asia by expanding its distribution pact with Hong Kong-based Celestial Tiger from China and Southeast Asia to all of East Asia, including Japan and South Korea. Celestial Tiger, which is partly owned by Lionsgate, will handle the company’s feature film and television content in the region.
