This is a clever little thing - you watch the Iron Man 2 trailer, and then you can click on various characters from the movie to get more info and pictures about that character, and you can even then have it cut right to the part of the video featuring that character, like if you're looking at Black Widow, there's a few different pictures of her, there's a description of her and then you can click on the video and it will take you right to the scene where she is fighting some people.

Pretty clever idea!
