X-Ray is a neat feature first introduced on the Kindle Fire HD last year that lets you get information from IMDB about actors in a scene while watching a movie.
Amazon said X-Ray will work on most of the popular shows in its library and will expand to more soon.
For now, X-Ray will only work on Kindle Fire HD tablets and the Amazon Instant streaming app on Nintendo's Wii video game console.
