The musical score for "Viewtiful Joe" was co-composed by Masakazu Sugimori and Masami Ueda. It was released alongside the score for "Viewtiful Joe 2" on a double album titled "Viewtiful Joe + Viewtiful Joe 2 Original Soundtrack" in Japan on 22 December 2004 by Suleputer. A music video is played within the game featuring a rap vocal song titled "Viewtiful World" composed by D.A.I. The video features a group of people, including Inaba himself, motion captured as some of the game's characters. On 11 June 2003, Avex released the video on DVD and released the song as a single. Both the North American and Japanese releases of "Viewtiful Joe" feature English voice acting in order to keep a "western comic book feel to game." Voice-over work in "Viewtiful Joe" was provided by Soundelux Design Music Group. Voice actors for the game include Dee Bradley Baker, Christina Puccelli, Gregg Berger, Mikey Kelley, Roger Rose, and Kevin Michael Richardson. Director Hideki Kamiya provides the voice for Six Machine.
