Leader Yang Sung Min of the CJ E&M casting team appeared on the recent airing of SBS's 'One Night of TV Entertainment' and provided interesting information about some of the casting to their most popular dramas. 

He stated, "There are almost no cases of casting the actor you first had your eyes set on for any production," explaining how they had initially offered Kim Woo Bin's role in 'Heirs' to Yonghwa, Suzy's role in 'Introduction to Architecture' to Seohyun, and Siwan's role in 'Misaeng' to Lee Jae Hoon.  Hey, but everything worked out so well!

Yang Sung Min said, "In the case of 'Misaeng,' we even sent in offers to a couple of actors apart from Lee Jae Hoon like Lee Jong Suk and Ji Chang Wook.  However, the way we see it, there is an owner for every casting."

Do you think the possible actors for the roles would have fit?  Like Yonghwa for 'Heirs' and Ji Chang Wook or Lee Jong Suk for 'Misaeng'?
