This idea is based on when your looking at a movie or tv show episode etc.
When your looking at the description, actor names, dates, etc. There is a picture in the background, but it only shows one at a time and if you want to see another you have to manually change it.
I have multiple backdrops for most all movies, as well as fanart.
My idea is;
To make use of those extra backdrops, fan art, and just turn them into a slideshow while looking at the description.
This is a great feature if you don't want to keep space for all the trailers, or just don't want them.
Backdrops are a great way to show off the title with the extra art and get a feel for the title, and make the description page a little more dynamic.
