Established in 2003, the "Left Motion Filmmakers Collective" has so far made two films: "Taipei, Looking Up" and "Street Survivor" With a leftist perspective, the Collective take documentary and feature films as their mission. This group of filmmakers should be seen as one single person, its members as body parts of the person. To make a film, the body parts gather up, form a human body, and then take up each responsibility in order to accomplish each task. Some becomes the head, others the hands; while some function as the feet and others as the heart. The assignment of tasks is not fixed, and members of the group are not definite. Members come and go, only forming by a shared belief. Such a "collective" does not even have a physical existence; it becomes a vessel for filmmaking only when there are films to make, letting those who share the same heart join or leave the vessel. It is, hence, a ghost or a spirit. A spirit is free; more importantly, a spirit should have its strength.
