Relationship Between the Trailer, Magazine Cover and Poster

Before I begin the actual making of the three products, an important quality that I believe must exist between them is the fact that they link together. This can be seen as a vital due to them being able to work as an end product to further enhance them from an advertising point of view. With them all working along side with each other, it will make each product stronger as it will help to anchor each of the other products and their selling points as they all have different target audiences theoretically. For instance the poster is directed at the mass public as they are put up everywhere, such as bus stops, train stations, billboards, shop windows etc... Since they are everywhere, they can not be targeted specifically at a certain audience. However, they still need to maintain their focal advertising points (e.g. for my film, the poster will still need to focus on horror). A trailer possess similar qualities to this, however it is restricted to a screen, e.g. on your computer or T.v. The magazine cover has a different audience all together as the people producing this are not the same as the people advertising the trailer and poster. This is because the magazine company itself would design the front cover and angle the film advertising in a way that would suite their specific audience.

With the trailer, magazine cover and poster having access to the public on such a large scale, it is important that they have united qualities. This has been done on many previous products, such as 'Hellboy 2':

These 3 products show a united front (even without the full footage of the trailer) this has been done through several techniques, such as, same font, main character being shown, statement about the film, same genre portrayed etc...
This is something that I want to show when creating my film trailer and ancillary texts.
