BUDAPEST — Miniseries “World Without End” will be the first production to shoot at a new mega sound stage at Hungary’s Korda Studios.Based on the novel by Ken Follett, “World Without End” is a sequel to the miniseries “Pillars of the Earth,” which aired on the U.S. Starz pay TV network last year. The newly completed 63,000 square-foot sound stage, one of the biggest in the world, is one of six sound stages located on a 86-acre lot just west of the Hungarian capital of Budapest. With the return of season two of the Showtime period series “The Borgias,” starring Jeremy Irons, Korda announced that it will be operating at full capacity for the remainder of this year. The studios’ recent surge in productions comes despite competition from Raleigh Studios Budapest, which has nine sound stages. This facility opened its doors last year and has serviced productions such as the 20th Century Fox and Regency feature “Monte Carlo.” Korda and Raleigh are facing off against Prague’s Barrandov Studios, which dominated the Central European industry in the 1990s. In an escalation of Europe’s studio wars, Korda will open the Euros4.47 million ($6.35 million) Korda Filmpark in June, the region’s first major studio amusement park.
