This is an interesting new way of marketing movies, and it seems to work in the interest of the big movie studios as well. Warner recently released Apps for both Inception and the Dark Knight. The Apps are free and are loaded with cool content like trivia, social netowrking features, games, soundtracks and the first five minutes of each movie.
You can also follow Tweets and other chatter related to each movie through the App. What's also interesting is that the App has it's own method of purchasing the movies from within the application as opposed to going through the iTunes Store.
Stay tuned as we go hands-on with the Inception App.
You can check the Apps out at the following links:
