MOSCOW — Poland’s biggest film showcase has changed its name.Wroclaw-based New Horizons Intl. Film Festival has dropped “Era” from its title after its key sponsor, local mobile operator Era changed its brand name to T-Mobile. The festival, which opens its 11th edition on July 21, will continue to co-operate with Polska Telefonia Cyfrowa — the operator of the T-Mobile brand in Poland. New Horizons, which combines film screenings with musical and artistic events, is the biggest film festival in Poland. Last year audiences reached 120,000. Around 430 films, including 230 features, from more than 50 countries are due to screen this year. Apart from the competition, highlights this year include a focus on Norwegian cinema and cult films including Japanese erotic “pink eiga” films, Eastern European communist-era “Red Westerns,” and retrospectives of the work of Terry Gilliam, Bruno Dumont, Andrzej Munk and Mariusz Wilczynski.
