Amazon is slowly implementing Amazon X-Ray across its platforms.
X-Ray is a joint venture with IMDB (the Internet Movie DataBase) to help you answer those nagging questions you have while watching a TV Show/Movie.
When you are watching via Amazon (on Fire devices or an Amazon Video app) all you have to do is tap the screen, and instantly it tells you what current actors are in this scene, what song(s) are playing in the background and other little tidbits about the shows.
I can’t wait until this is available on all platforms, and we no longer need to sit all show going “Where do I recognize him from?”….the answer by the way was Richard Kind and he was just in Inside Out.
