Group of Seven painter Lawren Harris’s glowing ice peaks and dreamy islandscapes take on truly transcendent dimension in this thorough new doc.

You’ll see how everything from the war to theosophy to a brush with a Scandinavian art exhibit fed his drive to simplify and abstract forms, endowing them with that incredible light and raising them to spiritual heights. This is detailed and educational stuff at a time when Harris’s work is at the height of its popularity. Along with ample shots of the artworks themselves, the film reenacts his trips to the Rockies and Lake Superior, gathers insights from experts (including Vancouver Art Gallery curator Ian Thom), and, of course, gets a few admiring words from his most famous collector, Steve Martin.
