Websites of upcoming films and how they attract their audience

Here are the websites for some comic book films coming out in 2013:

Iron Man 3:
http://www.imdb.com/title/tt1300854/
http://marvel.com/ironman3
http://en.wikipedia.org/wiki/Iron_Man_3

All of these websites attract their audience because they all describe the plot of the film in great detail, this will attract the audience because they will be able to see what the film is about and whether the plot sounds as good as the other films. They also all give a cast list, this way the audience can see who will be starring in it from the old films and what new actors will be in it, this could attract the audience because if they see that an actor they like is playing a role in the film, they'll be more likely to watch it.

Thor: The Dark World:
http://www.imdb.com/title/tt1981115/
http://en.wikipedia.org/wiki/Thor:_The_Dark_World
http://www.g4tv.com/thefeed/blog/post/730006/2013-movie-preview-thor-the-dark-world/

Again, all of these websites give a detailed explanation of the plot of the film, list the characters and they also show some photos of the making of the film, this will attract the audience because they will feel like they're viewing exclusive content, and if they like the look of the film they will be more likely to watch it.
