Synergy between trailer/cover/poster- How has this been maintained throughout

Synergy is the promotion and sale of a product (and all its versions) throughout the various subsidiaries of a media conglomerate. This creates an empire for the product and therefore reaches out to different audiences, by introducing the audience and getting them involved, it therefore means that consumers can be prosumers. Prosumers are consumers that are involved with a product and therefore a producer as well, an example of prosumers are when fans make fan made trailers for a certain film. For a film, synergy can involve posters, merchandise, trailers, magazines and many more. 

Harry Potter and the Deathly Hallows part 2 is a good example since it is the last instalment and had a lot of hype created around it. 

In March 2011, the first preview for Deathly Hallows – Part 2 was released revealing new footage and new interviews from the starring cast. The first US poster was released on 28 March 2011 with the caption "It All Ends 7.15" (referring to its international release date). On 27 April 2011, the first theatrical trailer for Part 2 was released. The trailer revealed a range of new and old footage. A month later, a set of many posters were released each illustrating a different character with the caption "It All Ends" and a background depicting the Battle of Hogwarts. The IMAX trailer for the film was released with IMAX screenings of Pirates of the Caribbean: On Stranger Tides on 20 May 2011. During the MTV Movie Awards on 5 June 2011, Emma Watson presented a sneak peek of the film.

An important part of synergy is to keep the marketing process consistent throughout to sell the product well enough. A product needs to be marketed through different types of media to reach different audiences whenever. HPATDH has been marketed through trailers, magazine covers, posters, merchandise and many more which has helped it become the big phenomenon that is is today.  It builds up the hype for the audience and gives it exposure to everyone, since it is the last film the audience will see these different types of media as collectables. The variety of subsidiaries are consistent in the image of the character Harry Potter by using the same image of him in the same clothes which makes it recogniseable to the audience. The different types of media have also shown a statement or catchphrase which seems coherent throughout such as 'IT ALL ENDS', 'THE LAST CRUSADE. THE PERFECT FAREWELL.' or 'THE EPIC CONCLUSION OF THE WORLDWIDE PHENOMENON'. They all seem to have a message of a farewell which sticks in peoples minds as they have to see the last instalment of a great film and therefore makes people see it.

The simple Empire magazine cover seems quite sad that it has ended, Empire have changed the house style of the text to gold which makes it seem specialised for the last film. The positioning of the actors are different as well compared to the second magazine cover which has been taken from the film. The fact that the first magazine cover isn't consistent with the rest of the subsidiaries makes it stand out and seem special. The colour of the media products have colours including blue and black mainly which give it a pessimisitic feeling throughout.

The trailer has the same Harry Potter themetune but it has been  updated to an eerie tune to add to the unexpected ending of the film. It created a daunting impression that has been consistent through out the films synergy.
