Hi, Jin! I didn't watch it, but I have some interesting information about it. So, I wrote this essay right after today's class.
This movie is famous because it's evaluated as a well-made movie, and all the actors' performances are wonderful. I'd like to tell you something about the main actor, Choi Min-sik, who played the role of the killer. This is a pretty famous story in Korea. Choi Min-sik went through serious aftereffects after he portrayed the killer. He felt a violent urge when a man, whom he met everyday, called him without honorifics in the elevator. He also said in an interview, "I felt fake blood as real blood on the movie set, and I was disgusted."

Hi, Jin. Thank you so much for this. I think Choi Min-sik was so immersed in his role as the killer that’s why this happened. It only shows that he is a very good actor. I think I will look for his other movies and watch them. Again, thank you for writing this essay. Have a great weekend, Jin! :)
