The principal characters in this 2005 German feature are two troubled, rebellious teenage girls who meet in a Berlin park and fall in love and a Frenchwoman who’s persuaded that one of them is her long-lost daughter, abducted as an infant. All three are lost souls who sometimes project their fantasies onto other people. Initially director Christian Petzold appears to be cross-referencing Celine and Julie Go Boating with the two girls, but the lack of any humor or sense of fun makes the allusion feel pointless. The enterprising experimental filmmaker Harun Farocki collaborated on the script, said to be derived from one of Grimm’s fairy tales, but I found most of this intractable. In German with subtitles. 85 min. (JR)
