Trailer- Brief Plot Synopsis Help

Before beginning to write our plot synopsis, we decided to conduct some research into what kind of this should be included in synopsis, to make is successful.

Below are the websites that we used for this research:

This research benefited us, as it showed what should be included and what should not be included. Examples of these do's and don'ts are:

Do Make sure that the synopsis includes exclusive details of the story of the film (with no commentary)

Do Try and get the first line to be one or two sentences long and contain irony if at all possible.

Do establish what your hero is trying to achieve during the course of the story. Get the reader quickly invested in whether or not the protagonist will succeed.  

Do write in third person, present tense.  

Don’t mention all of the characters, just the main ones included the protagonist and antagonist.

Don’t mention too much about the plot. Talk about subjects that won’t give things away. You want to write something that will get the reader to watch the movie, without giving away the entire story.
