Kamen Rider: The First is a 2005 Japanese tokusatsu superhero film. The film is a reboot adaptation of the television series Kamen Rider, though there are many differences between the film and the original programme; some of these, however, are due to a closer reliance on the original Kamen Rider manga by Shotaro Ishinomori. Written by Toshiki Inoue and directed by Takao Nagaishi, the film stars Masaya Kikawada as Takeshi Hongo/Kamen Rider 1 and Hassei Takano as Hayato Ichimonji/Kamen Rider 2.
