Jumong/The Book of Three Hans Fast Facts

Hello just a short post and I couldn't remember for the life of me where I "got" these. If you know where please do tell. ^^

1. There were casting changes in the drama. The role Buyoung (played by newcomer Im So-young) was an important character in the drama ( since Buyoung played an important part in Jumong's life in history) but since the actress can't do her acting well enough, her character was removed and a new one replaced her Ye Soya (played by Song Ji-hyo of Goong).

2. 30% was shot in China and 70% was shot in Korea.

3. That Oh Yeon-soo (Lady Yu Hwa) plays Jumong's mom despite the fact that she and Jumong himself (Song Il-kook) are both 35.

4. The production staff consists of director Lee Joo-hwan (Miss Mermaid/Irene), writers Choi Wan-gyu (All-in, Love Story in Harvard, Hur Jun) and Jung Hyung-soo (Damo).

5. The production cost amounted to 30,000,000 US dollars.

6. This TV series is a 50th Anniversary Special of MBC Korea. Well, it's no wonder the sho is so good.
