Star Wars: Episode I – The Phantom Menace has Qui-Gon Jinn test the blood of a young Anakin Skywalker for midi-chlorians as a means of gauging his potential strength in the Force. Later, he explains them to Skywalker, describing them as having a symbiotic relationship with the beings they reside in, and that one can connect to the Force by “listening” to them. The Force was described in spiritual terms throughout the original Star Wars trilogy, but midi-chlorians seemed to contradict this, making the Force seem too mundane for many viewers.
