It is my favourite fictional setting.
It has some pretty unique things like the Skaven or the Chaos gods, which are the main force of evil and are basically created by negative human emotions. It has a vast amount of lore (we're talking probably more than 100 books) and still feels like classic fantasy. It is dark and gritty, but is relatable, because the main protagonists of many stories are ordinary humans.
I'm not aware of any movies, but the Total War games are very popular right now. Here is a recent trailer: YouTube: YaLtE3cCEIs It shows the forces of Chaos, coming from the cursed wastelands in the far east, fighting Kislev, which is a snowy, slav-inspired faction.
Vermintide was also a big hit: YouTube: KxTaQmhztVQ
