Lars von Trier
In The Five Obstructions (2003), Trier challenged his older colleague Jørgen Leth to remake the short film The Perfect Man (1967) based on changing playing rules. Dogville (2003), about society and the stranger, is played on a stage floor with white lines and selected props; it, together with Manderlay on freedom and slavery, is the never-ending trilogy about the United States during the '30s crisis.
