Centered in the 2,000-year-old Portuguese city of Guimarães, three renowned directors explore 3D and its evolution in the world of cinema. Peter Greenaway’s Just in Time is an all-consuming history lesson; Jean-Luc Godard deconstructs cinema’s relationship to perspective in Les trois désastres; and Edgar Pêra’s Cinesapiens lightens the mood with some truly wacky visual fun and over-the-top phantasmagoria. Each asks, in its own way, how 3D affects the audience and its visual perception. 2013, DCP, 70 minutes.
