Luna Wedler in a scene from Silent Friend An elegant, enigmatic examination of humanity’s connection to the natural world, Silent Friend is the latest film from Hungarian auteur Ildikó Enyedi, and her highest-profile effort, perhaps, since her 1989 feature debut My Twentieth Century. Silent Friend centers on an enormous ginkgo biloba tree that has been growing on the campus of the University of Marburg in Germany since at least 1832, the date embossed on a plaque embedded in its trunk.
