Lucy Mulloy’s “One Night,” a U.S.-Cuban-British co-production about two Cuban boys who build a raft to sail to Florida, and Olivia Silver’s U.S. family drama “Arcadia” are among features unspooling in the Berlinale’s Generation children and youth sidebar.In a world premiere, the newly restored 3D version of Da Su’s classic Chinese animated film “The Monkey King: Uproar in Heaven,” released in 1961, is also screening in the section. “One Night” is one of seven selections announced Thursday that will screen in the older-skewing Generation 14plus section. Others include Simon Aboud’s U.K. heist pic “Comes a Bright Day,” starring Craig Roberts, Imogen Poots and Kevin McKidd; Robert Sarkies’ Kiwi entry “Two Little Boys”; and Pietra Brettkelly’s documentary “Maori Boy Genius,” also from New Zealand. “Arcadia” screens in the tyke sidebar, Generation Kplus, along with Martin Hoegdahl’s Swedish family adventure “The Ice Dragon,” Indian helmer Rajan Khosa’s “Gattu” and Remi Bezancon and Jean-Christophe Lie’s French-Belgian animated pic “Zarafa,” about a baby giraffe that travels from Africa to Paris as a gift for the king of France. A total of 56 short and feature films from 32 countries have been selected for the Kplus and 14plus competitions, including 12 feture directorial debuts. In addition to “The Monkey King,” Cornelia Gruenberg’s German documentary “Fourteen” will also unspool out of competition. The Berlinale runs Feb. 9-19.
