Not the strongest von Trier film but maybe the one with the most potential. Content-wise, it's nothing special but it's told in a cool way. I wish he would have explored this style of storytelling more in his other films. You can watch it here: http://www.ubu.com/film/trier_orchid.html
Made by a talented student already familiar with the key works of Bergman, Fassbinder, Tarkovsky, etc - but too one-dimensional to compete with such vaunted influences - the film plays best as a cracked allegory on the themes of obsession, identity, guilt & decay. The inclusion of cross-dressing, animal cruelty, auto-erotic asphyxiation & Nazi chic show the young Trier's propensity for provocation to be fully formed.
