Teaser Trailers and Theatrical Trailers

A teaser trailer is a short trailer that is often used to help to advertise an upcoming film or other media form. It can be released months before the due date of the official film to help create anticipation and interest from the target audience. A theatrical trailer is a much more in depth well revised longer trailer which tells us more about the plot of the film and gives us exact dates when it will be out.
A teaser trailer is a lot shorter compared to a theatrical trailer. The teaser trailer's main purpose is to 'tease' the audience with short snippets from the movie and by not revealing too much of the plot. It is normally under two minutes whereas a theatrical trailer is usually much longer, sometimes up to four or five minutes.
Distinctive features of  a teaser trailer are: The length of the trailer which is usually under two minutes, in teaser trailer the produces and actors.acresses are exploited to create interest from the audience. e.g a famous actor such as Johnny Depp would instantly get audience interest due to his wide variety of films. The trailer would also show when the film is going to be out e.g 'This Summer' where as a theatrical trailer usually tells you the month is will be out or even the date e.g 'August 23rd'.
At the beginning of the teaser trailer we are instantly being exploited the directors' name and possibly his previous work e.g 'From the makers of...' The theatrical trailer is much more heavily edited with voice over's and inter titles where the teaser trailer does not contain all these things. We can relate the main protagonist in the film by watching the theatrical trailer as it reveals more about the plot than the teaser trailer.
