A movie is not considered literature. Literature, by definition, is something that you can read. So, examples would include novels, short stories, poetry, and the like. Even scripts, for plays and movies, would be considered literature. I mean, we read Shakespeare in our English classes around the world - so of course the scripts are literature.
Movies, however, are a different kind of media. The word “movie” is actually a portmanteau of “moving” and “picture”. (A ‘talkie” by that same standard is then a “talking picture”.) This is something we watch, which defeats the meaning of literature. Furthermore, not all movies are based on books, but books are almost always turned into movies or television shows. Examples include Sherlock Holmes, “Pride and Prejudice”, and “The 100”.
