Now this is some interesting casting news! Actor Lee Bum Soo and Girls’ Generation‘s YoonA are in talks to lead a new KBS drama “Prime Minister and I.”

“Prime Minister and I ,” to be written by Kim Eun Hee, is described as the Korean version of the famous story “Sound of Music.” It will follow the love story between a prime minister and a governess who in the past gave up her dream to become a musical actress.

This drama is being produced by SM C&C, the subsidiary of YoonA’s agency SM Entertainment, which might explains YoonA’s possible casting. 

Lee Bum Soo’s reps have stated that the actor is merely reviewing the role; nothing has been decided yet. The actor is currently busy filming the movie “God’s Trick.”

Lee Bum Soo was born in 1970 and YoonA in 1990, meaning there is 20-year age gap between them if the casting happens. While the original “Sound of Music” story also depicts a large age-gap, what do you think guys? Too much? Or does age not matter as long as there is chemistry?
