We've seen zombies on trains, in run-down apartments, and in the medieval era; now get ready for zombies in high school. Netflix's latest hit k-drama All of Us Are Dead shows a new spin on South Korea's excellent zombie content, following a group of high schoolers stuck at the center of a deadly outbreak. Based on a popular digital comic from WEBTOON, "Now at Our School" by Joo Dong-geun, the students at Hyosan High School have to figure out how to survive when their neighborhood is shut down.

For the cast, the series gathered some of the most talented young actors in South Korea, as well as established stars to play the adults. For those already making Squid Game comparisons, the drama even includes one of its breakout stars. Here's everything we know about the cast of All of Us Are Dead.
