The Green Fog (2017) is a mind-bending walk through the iconic narrative arc of Alfred Hitchcock’s Vertigo (1958). Commissioned for the closing night of the 2017 San Francisco Film Festival, director Guy Maddin (with co-directors Galen Johnson and Evan Johnson) pays a wonderfully subversive tribute to Hitchcock’s San Francisco-centric film by stitching together footage from movies and tv shows filmed in the Bay Area. Through the scrim of cut up and reworked scenes, the emotional peaks and valleys of Vertigo’s plot materialize. However, this approach never turns into a trivia game for cinephiles. Indeed, a particularly precocious cineast could spend the entirety of The Green Fog recalling the classic films that appear on screen (over 100 in total), pulling each title from the recesses of her mind. However, in traditional Maddin fashion, a more conceptual and active level of movie watching is required.
