Underground
The term describes a range of filmmaking styles that are generally quite different from, and often opposed to, the practices of mainstream commercial and documentary filmmaking. Avant-garde is also used, for the films shots in the twenties in the field of history’s avant-gardes currents in France, Germany or Russia, to describe this work, and "underground" was used in the sixties, though it has also had other connotations. Today the term "experimental cinema" prevails, because it’s possible to make experimental films without the presence of any avant-garde movement in the cultural field.
