This Saturday, the drama series "MR.BRAIN," starring SMAP's Takuya Kimura, will premiere on TBS. The cast already includes several other popular stars, such as Haruka Ayase and Hiro Mizushima, but during a recent press event it was announced that each episode will also feature big-name guests.

Last week, it was revealed that KAT-TUN's Kazuya Kamenashi is scheduled to appear in the show's third episode. Now, it is known that the first episode will have appearances by Ebizo Ichikawa, Ryoko Hirosue, and others, while the second episode will bring on musician Gackt.

TBS is hoping to draw very high ratings for the series, which airs in the network's Saturday night time slot.
