Vanishing Landscapes(2013)

It takes courage to shout "Action!"... Much more courage to never say "Cut!"

A mockumentary about three young student filmmakers as they make a movie about an alleged film director living obscurely in a Buenos Aires mental hospital. In their visits to the mental hospital, the three students will forge a very special relationship with the self-styled former film director as they follow different clues and strategies to discover his 'true' identity.
