The cast of upcoming tvN legal drama Big Mouth just exploded this week with so many recognizable faces joining leads Lee Jong Seok and Yoona. I guess filming is starting soon lol. Every one of these supporting leads have other dramas and movies going on as well so it’s really a solid collection of currently hot talent. Joining the cast is Kwak Dong Yeon, Kim Joo Hun, Ok Ja Yeon, and Yang Kyung Won, each with recently big drama hits this year in Vincenzo, Mine, and Start-up. Big Mouth is definitely shaping up to be one of the highest profile dramas around what with it being Lee Jong Seok’s post-military comeback project and partnered with Yoona there will definitely be two fandoms working double time to create buzz. I’m just praying for a great drama with a solid storyline.
