What is a movie trailer?
So this is the part where i would explain what a trailer is. this is here so that the audience has some sort of sense of what I’m on about. Also i put in the reason I’m drawn to the subject.
Movie Trailer: Trailers or previews are film advertisements for feature films that will be exhibited in the future at a cinema, on whose screen they are shown. 
I’ve always held a certain fascination with movie trailers. I don’t really know why, I just have. Maybe be its because they can make you happy, sad, excited, queasy, give you a thrill, give you a chill, all in two and a half minutes. I even always like to turn up early to see a film just so we can catch the previews.
Everyone has seen a movie trailer… well anyone who isn’t living under the proverbial “rock”.
They are everywhere, at the movies, on DVDs, of the some ten million online videos that are watched, movie trailers rank number three. 
So you must have at least seen one.
Trailers are a very popular and influential “marketing tool”. And yet there is not much actual attention payed to the trailers themselves. Though movies are praised, condemned, or both. Trailers aren’t given a second thought, though without their trailers the movies would not be what they are today.
So I have taken up the duty of giving you a little background on these fantastic things, and so next time you see one, can hold a little appreciation for them.
this is the list of all the trailers mentioned and a link to see them. they all have the title of the movie, the year and what i could and did use them for. also after it is the bibliography.
