When citing film and other media, use the citation form for the format in which you watched the work being cited. In other words, if you watched a film on DVD or VHS, cite it, as a DVD or VHS (not the film original). If you are citing a trailer for a theatrical movie that you watched on the internet, use the citation format for online resource. If you saw a movie in the theater, use citation format for film.
