Frederick Wiseman’s glorious new film is about the energies of, and around, painting—discussing, framing, mounting, lighting, repairing, restoring, creating, and, perhaps most of all, looking at painting. This is a film of color, light, and sensuous action, in the artwork on the walls and within the universe of London’s great National Gallery itself. In fact, the dividing line between the paintings and the life around them dissolves almost immediately, as Wiseman attunes us to pure response: the individual’s response to the paintings, the painter’s response to the subject at hand, the filmmaker’s response to the people, activities, and light around him. There are discussions of budgetary concerns and social media, but the film and the people within it are always drawn back to the magnetic power of the art itself. National Gallery is a film of faces: the faces of those looking and the faces of those who look back from the canvases, in an endless, joyful exchange.
