Blue Submarine No. 6/Episodes

Blue Submarine No. 6 is a 4-part OVA series, that spans 120 minutes. The series was produced by Gonzo. The series was released in the United States on April 4, 2000. It uses a hybrid approach, combining 3D computer graphics with traditional animation, and is a pioneering example of this technique. It aired in the United States on Cartoon Network's Toonami block from November 6, 2000 to November 9, 2000. The jazzy and atmospheric score was provided by rock n' roll big band The Thrill.

The series was initially licensed by Bandai Entertainment until their shutdown in 2012. Discotek Media has since licensed the OVA and re-released the series on DVD and Blu-ray in 2013.
