It was indeed a big surprise to everyone to know that Lee Jong Suk rejected an offer to him to play as the lead role in the upcoming movie, "Dream". Lee Byeong Heon is the director of the movie, and is best known for his previous film, "Twenty" and "Be Positive".
As of now, Lee Jong Suk is reported to be busy filming her upcoming drama series together with Suzy Bae. And because of this, most people believe that this is the main reason why he declined the offer for the lead role.
YG Entertainment, the management company of Lee Jong Suk, says that it was never confirmed that Lee Jong Suk will be appearing in "Dream". The company then added that Lee Jong Suk was still reviewing the offer during those times.
