One nonfiction film that truly creates a narrative journey, My Architect is filmmaker Nathaniel Kahn's engrossing search for his father. Louis Kahn, one of the most celebrated architects of the 20th century, died in 1974 and left behind a highly compartmentalized life, including two children born out of wedlock to two mistresses. Nathaniel interviews the members of this somewhat puzzled family, but his deepest experiences are visits to the buildings that his father made (such as the grand Salk Institute in La Jolla, California), culminating in an emotional trip to Bangladesh. Here, Louis Kahn designed a massive government complex, a soaring achievement (and fascinating paradox--a Muslim capital designed by a Jewish man). This film asks: where does an artist truly live? In his life, or in the work he leaves behind? Nathaniel Kahn takes an amazingly even-tempered approach to this, given his personal stake in the story, and the result is a uniquely stirring movie. --Robert Horton
