In film, however, there is only a finite amount of content. You can’t just watch something unrelated to the story. The film is the story. Bonus content and features are sometimes packaged with films, but this optional content is not as big of a component to the film as open-world exploration, multiplayer, or arcade modes are to videogames. Anything over the top than a sly reference will feel like advertising, as opposed to the slight nods to the audience they’re supposed to be.
