Probing his phobias and neuroses, a documentary on this generation's noble scion of Scandinavian cinema--Lars von Trier who directed "Breaking the Waves" (Denmark, Norway, Sweden, France/1996), "Zentropa" (Denmark, France, Sweden, Germany/1991), and "The Kingdom I & II (Demnak/1994;1997)." A child of Jewish parents whom he describes as "radical middle class," who gave him an excess of freedom, he saw fit to add "von" to his name. Among von Trier's many idiosyncratic positions is his description of women as "difficult to understand... like swans." His colleagues' anecdotes regarding the enigmatic Dane are all over the map: he's a genius, a madman, a solid bourgeois who likes to trim his hedges wearing bedroom slippers.
