It was announced on Monday that Shinichi Tsutsumi and Yasuko Matsuyuki have been cast in the movie "Yougisha x no Kenshin," based on an award-winning novel by Keigo Higashino.

The novel is part of the "Tantei Galileo" series, which was the basis of a Fuji TV drama series this past fall. The drama, titled "Galileo," starred Masaharu Fukuyama as the brilliant physicist Manabu Yukawa, who helps a detective (Kou Shibasaki) solve baffling crimes.

Fukuyama and Shibasaki, along with the main cast of the TV series, are reprising their roles for the movie. Matsuyuki plays a suspected murderer, while Tsutsumi plays Yukawa's true opponent, a mathematical genius.

The movie, which was announced in October, is being directed by Hiroshi Nishitani. Filming has been under way since mid-January, and production is expected to be finished in time for a fall release.
