released by Warner Bros. As with the previous films, EA Games produced a video game based on the film. On 10 March 2009, it was announced that there would be a video game soundtrack, which was released on 17 March 2009. On 27 March, six character posters were released: Harry, Dumbledore, Ron, Hermione, Draco and Snape.
