Sho Sakurai stars in "The Quiz Show"
Fri, March 13, 2009 (7:07pm EDT)

Arashi's Sho Sakurai has been chosen to star in the NTV drama series "The Quiz Show." The show is a prime time version of last summer's late night drama "The Quiz Show," which starred Jin Katagiri and Shigeyuki Totsugi.

In the new version, Sakurai plays the host of a live TV quiz program. On the show, contestants who achieve 7 correct answers win 10 million yen, and those who get 8 correct answers will have one of their wishes granted by the TV network. But while the questions start off innocently enough, as the game progresses, the questions gradually delve into the contestants' past crimes or indiscretions, presenting them with the dilemma of having to confess their guilt in order to win.

Sakurai's character also has a mysterious past. Before becoming the show's host, an accident had left him in a vegetative state for six years, which also resulted in him losing most of his memories.

The supporting cast includes Kanjani8's Yu Yokoyama as the show's director, Aya Matsuura as a rookie assistant director, and Miki Maya as the producer. Broadcast begins on April 18 in NTV's Saturday 9pm time slot.
