Comedian Jung Hyung Don will be the MC for MBC’s upcoming two-episode pilot show “Sherlock’s Room” (working title).
A source of MBC confirmed the news on June 16, and explained “The show is mainly about solving crime.” The source also revealed that the show will have Jung Hyung Don as the sole, exclusive MC with guests.
This is Jung Hyung Don’s first time returning to MBC since leaving “Infinite Challenge” in November 2015. Jung Hyung Don left the entertainment industry temporarily at the time due to panic disorder, and returned to TV last October through MBC Every1’s “Weekly Idol.”
Meanwhile, “Sherlock’s Room” is scheduled to air early July.
