research and development - teaser trailer analysis

For my film trailer I will be making a teaser trailer. the main differences between a teaser trailer and a full theatrical trailer is that a teaser trailer is only a minute or 1.5 minutes long so doesn't express much about the film. instead of showing incredible amounts of the film, I will be showing little parts to create a sense of mystery and thus enticing the audience into seeing the film. Furthermore, I personally feel that if the audience is shown too much of the trailer then they wont both seeing the film at all.
