The Battleship film campaign used famous actors and dramatic images from the film in trailers and posters on social media sites like Facebook and Twitter to promote it to a broad audience. They also aired frequent trailers before similar genre films in theaters and on television in the US. Film trailers are made to create awareness and interest in a new film so that people will want to see it when it is released. They are snippets of clips and scenes from the film with titles and audio edited together, usually a few minutes long. Trailers are shown on TV and before other movies in theaters, often before films of the same genre, to reach the intended target audience. They are generally released 1-2 months before the film to build interest
