Wim Wenders had planned for years with German Neo-expressionist choreographer Pina Bausch to make a film of her work, but Wenders didn't know how he could do it justice. Then he saw U2 3D (2008) and knew that digital 3D was the technology he needed. Unfortunately, as technology caught up to Wenders' vision, Bausch passed away, and Pina (2011) morphed from just a document of her work into a tribute from Wenders and Bausch's dance troupe. What they create together is an overwhelming piece of art.
