THEORY -> WHO?

In general, the point of trailers are to publicise the film but in a more exciting and thrilling way. Different types of people like different genre of films and whilst every individual has a preference, 0there are certain features that will have a wide appeal to specific groups of people. It all depends on what the film's storyline; If it is an action packed war film, usually it would stereotypically appeal to male audiences. However a romance movie on valentines day would normally appeal to a female audience - also stereotypical. This is why each production company has to tailor their trailers to their specific target audiences just like the film.
