Top Korean actors playing killers is a totally “in” thing now and it almost always works because it goes against type, whether visuals or just the idea that an A-lister would deign to play the antagonist. Add another one to the list as K-actor Ahn Jae Wook has been cast as the serial killer antagonist in the upcoming 2021 thriller drama Mouse. He plays a former top hospital doctor turned serial killer in a drama about genetic testing being able to ascertain whether the baby carries the serial killer gene and asks whether the parents would have the baby. The leads are Lee Seung Gi, Lee Hee Joon, Park Joo Hyun, and Kyung Soo Jin with the script from the writer of Black, God’s Gift: 14 Days, and the 2008 Lee Jun Ki version of Iljimae.
