I watched this movie in 2005, I liked, the plot starts like black comedy, after gets serious. Those things really happens. People die, disappear, wakes up without liver. Because there is a market. Some countries like the US if you are rich enough you don't need to go in waiting list for transplant.
In the 80s in Brazil they discovered children they thought were being adopted were killed for their organs.
It is serious.
The time I watched this movie only Song Kang Ho and Park Chan were famous. After watching Beyond Evil I wanted to watch Shin Ha Kyoon in others dramas, I was surprised to see another of my favourite actress was in this movie, I love Bae Doona. She and SHK were promising since their early 20s.
What is amazing this movie still relevant. Good thinks doesn't get obsolet
