To demonstrate the movie to greatest benefit, special screenings can happen in lavish, low seat-count theatres with very large quality (sometimes particularly certified) projection and audio equipment, and may come with food and beverage and spoken opinions by producers, writers, or actors.

Special screenings occur beyond regular revealing hours. The kinds of screenings are presented within their arrangement in the development of a film. For ancient edits of a movie, casual evaluation screenings have been revealed to little target viewers to judge whether a movie will need editing, reshooting or rewriting.

At this phase the movie might be incomplete, with incomplete or missing special effects shots or audio effects, or dialog not yet rerecorded. Responses are recorded. Audiences could be asked to not explore the movie. A movie may go through evaluation screenings.
