[Advent Drama Calendar 2020] Day 13: Which actor took the most risks in a role?

I'm not sure if that was a risk per se, but a significant departure from the usual suave emploi.

1. Lee Dongwook as Seo Moonjo (Strangers From Hell, 2019) 

 

The calm voice, the overwhelming presence, the clearly unhinged neurons. He was freakishly nightmarish. And it was easy to turn it into a grotesque but LDW reined in the emotions and it suited him perfectly all of the sudden.
