Train to Busan, released in 2016, went on to become a massive hit in various countries around the world. It's said the budget of Peninsula is roughly $16 million, which is double what the original cost to produce.
While it is being billed as a sequel, director Yeon Sang-ho cautions that it is not a continuation of what happened in Train to Busan, but it "happens in the same universe." The story of Peninsula is set four years after the events of the first movie. It centers on a former soldier who has managed to escape the devastated Korean peninsula. But he is given a mission to go back and surprisingly meets up with survivors.
Zombie movies...I guess we still watch them.
