For “The Monuments Men” by George Clooney I also worked as HoD sculptor on location around Gosslar, Harz. One of the challenges there was to build several fake trees into the forrest, that should brake off through an explosion in the next scene. We collected original bark, puzzled the pieces together to make a positive mould, casted it in silicon and produced plaster bark, wich was mounted a wooden underconstruction. The artifical trees were mounted on origial tree stumps. For the second scene, these trees were cut and prepared with splints and pieces collected from broken trees around.
