Written by Lars Von Trier and Thomas Vinterburg
- Filming must be done on location. Props and sets must not be brought in. If a particular prop is necessary for the story, a location must be chosen where this prop may be found.
- The sound must never be produced apart from the images or vice-versa. Music must not be used unless it occurs within the scene being filmed, i.e., diegetic.
- The camera must be a hand-held camera. Any movement or immobility attainable in the hand is permitted. The film must not take place where the camera is standing; Filming must take place where the action takes place.
- The film must be in color. Special lighting is not acceptable (if there is too little light for exposure the scene must be cut or a single lamp be attached to the camera).
- Optical work and filters are forbidden.
- The film must not contain superficial action (murders, weapons, etc. must not occur).
- Temporal and geographical alienation are forbidden (that is to say the film takes place here and now).
- Genre movies are not acceptable.
- The final picture must be transferred to the Academy 35mm film, with an aspect ratio of 4:3, that is, not widescreen. Originally, the requirement was that the film had to be filmed on Academy 35mm film, but the rule was relaxed to allow low-budget productions.
- The director must not be credited.
