Creating a film is more than just telling a story, it is about creating a whole world with identifiable rules and properties. Though this will usually resemble the real world, it is important to respect all of the events that occur with the proper principles of cause and effect. What this means is continuity, in all its forms, must be maintained if the audience is to suspend their disbelief and actually absolve themselves into the film they are watching. If you pay attention to certain parts of the film you can help to avoid continuity errors.
