Moreover Jurassic World was due to be released in the summer of 2005, but instead they spent a decade alternating and improving the script. This helped to make the film successful because it got countless positive reviews from various film critics, who commented on how well it had been written. I think the fact that it was announced that the film would be released in 2005 but then got pushed to 2015, made the Film more successful because of how many Jurassic Park fans had to wait to continue their epic adventure on the fictional island of Isla Nublar. As a consequence of this I feel it made people very eager to want to see it by the time the release date came. Also during the development of the script, many famous actors such as Keira Knightley, dropped hints that they may be pursuing a role in the upcoming film, therefore it was already publicised, to Jurassic Park fans, as I 'Must see film'.
Furthermore the filmmakers spent far too much money on the making and production of the film, to not splash out on the advertisement too. After all how could they expect the film to be a massive hit if no one knew about it? They knew they had to do something big. Universal spent a total of $34.9 million on TV advertisement for the film. Jurassic World teamed up with big companies such as Mercedes-Benz, in an attempt to gain more publicity for the impending release. Universal also took it one step further when they put a dinosaur container, from Jurassic world, in the middle of Waterloo Underground, as a reminder of the sequels upcoming release.
In conclusion, all parties involved in the making and production of this film worked extremely hard to make it a successful Blockbuster and it clearly paid off when it busted Box-Office records, upon its release in May 2015.
