Family Tree (French: L'Arbre et la forêt) is a 2010 French film directed by Olivier Ducastel and Jacques Martineau. It drew its inspiration in large measure from the life of Pierre Seel, an Alsatian homosexual deported to the camp of Schirmeck, who wrote of his experiences in a book, Moi, Pierre Seel, déporté homosexuel. The film won the Prix Jean Vigo in 2009.
