Language
Film is considered to have its own language.

Criticism

Film criticism is the analysis and evaluation of films. In general these Works can be divided into two categories: academic criticism by film scholars and journalistic film criticism  that appears regulary in newspaper and other media.

Montage

Montage is the technique  by which separate pieces of film are  selected, edited, and then pieced together to make a new selection of film.  A scene could show a man going into a battle, with flashbacks  to his youth and to his home-life and with added special effects, placed into the film after filming is complete. As these were all filmed separately, and perhaps with different actors, the final version is called a montage.
