Since the ’90s, K-culture has grown into a global phenomenon that the world just can’t seem to get enough of.

Asian horror stories in general have been well-received for a long time. With hit films like the original Japanese horror film Ring and the immensely popularKorean zombie flick, Train to Busan inspiring mainstream Western remakes, the popularity of the genre was well-placed to move into a series format too. In 2022, the Korean zombie show All of Us Are Deaddid just this and has been nothing short of a revelation since. The show is based on a webtoon of the same name and now usually sits in Netflix’s top five most-watched non-English shows ever.

The show has unsurprisingly been confirmed for a second season. If you’re thinking of catching up on this bingeworthy show before then, now would be a great time to do it. Here’s a cast and character guide for All of Us Are Dead to get you started.
