In the 1990s Iida branched out into television, creating the series Night Head (1992-1993), which would go on to spawn an entire franchise including a made-for-TV movie of the same name in 1994 as well as manga and books. An anime series, Night Head Genesis, was subsequently produced in 2006. Other notable productions include the 1998 Rasen, the original sequel to Hideo Nakata's film Ring (before Nakata directed the better known, and otherwise unrelated, Ring 2 in 1999), and the police procedural/horror Another Heaven (2000). Rasen was based on Koji Suzuki's second novel of his Ring Trilogy of the same name, also known as The Spiral. Another Heaven was based on one of Iida's own books.
