You have to tag the actor/actress in the backdrop. Otherwise it won't work. To add an actor to the backdrop you need to click the image when viewing the main page of the movie. Then a window will open and you will find an option to add a person. Let me know if you get it to work.

Also good to know, it only 'works' for backdrops of movies and tv shows, not for the episode stills of tv shows! :)

Thanks. I suspect this feature would be used more often if more people knew how this worked.

Thanks a lot. It's work well. But i have a lack of backdrop in my favorites actress/actors plug. And it's take some times to add it ;)

Good! Remember to keep the quality up for the backdrops. We have a very high standard overall, even though we usually allow slight lower quality for older films.
