Watch out for squirting blood! Takashi Miike — Japan’s prince of pain and baron of bloodshed — is going 3-D. Film Comment reports that Miike’s next film will be “Seppuku,” a samurai revenge-flick shot in 3-D. It will be the follow-up to “13 Assassins,” another Miike samurai flick, which was made in plain old 2-D. The prolific Miike is noted for violent cult films such as “Audition,” “Ichi the Killer” and “Gozu.”
