Different Film Marketing Methods and what they are suitable for

The marketing methods I can remember from today are viral, film websites, trailers, merchandise, video games, posters, books and toys.
Today I learnt that some film marketing methods are suited to particular audiences. For example creating toys for a film is best suited to a film whose audience is a young age up to 12 years of age because they are the main audience who buy toys so they would find out about the film and want to see it.
Creating a poster in a men's magazine for a film is best suited to a film whose audience is men above the age of 18 and because they are the primary audience who buy these magazines and enjoy these types of films.
Today I learnt that some film marketing methods are suited to particular genres of film. For example having a video game based on the film is best suited to a film which is from the action genre because they will enjoy be part of the film and being in control so after playing the game they will watch the film.
Having a trailer before a comedy film is best suited for a film which is from the same genre because fans of comedy will see the trailer and want to see the film themselves.
