The two directors of 'Cloud Atlas' and actress Bae Doo Na participated in filming for MBC's 'Knee Drop Guru'.

Bae Doo Na had recently acted in the Hollywood hit movie 'Cloud Atlas'. On December 13th, she held a press conference for the Korean release of the movie along with the directors and fellow actor Jim Sturgess. It seems like that the press conference wasn't the only thing that the 'Cloud Atlas' team participated in while in Korea, because a representative from 'Knee Drop Guru'�revealed, "Bae Doo Na and the Wachowski siblings were at the MBC Ilsan Dream Center today. They're currently filming for the show."

The representative revealed, "We recruited the Wachowski siblings in top secret. This will be the only show that they will be appearing on while in Korea."

The episode is scheduled to air in early January.
