Amazing casting. Wonderful to watch a 77 year-old MIT PhD and IIT-Mumbai gold medalist act in the role of the Guruji (a rough equivalent a master in the field). He was not acting most of the time, he was actually singing the ragas! I suspected this while watching the film and wondered if the actors were being helped by playback, which would have been difficult to accomplish Aging process of Aditya Modak another real life singer, is a tribute to the make-up department. The real winners of the film are the slow-motion sequences of the lonely motorbike rider in the night with the sitar music on the soundtrack--one of the finest urban sequences in Indian cinema captured by the young Polish cinematographer Michal Sobocinski. Good editing and screenplay by the director Chjaitnaya Tamhane. Thanks to the Mexican director Alfonso Cuaron ("Roma," "Y ti mama tambien"), who partially bankrolled the film. India looks so clean and wonderful in this film!
