In March 1992, Gainax started planning and producing an anime movie called Aoki Uru ("Blue Uru"), which was a sequel to Royal Space Force: The Wings of Honneamise set 50 years later. It would follow a group of fighter pilots like Oritsu. However, production stopped in July 1993 because Gainax could not afford to make a full-length anime movie; many of its core businesses were shutting down or producing minimal amounts of money. At the 2013 Tokyo Anime Fair, Gainax announced that they would finally produce Blue Uru with Honneamise veterans Hiroyuki Yamaga as the director and screenwriter and Yoshiyuki Sadamoto as the character designer, but without Hideaki Annos involvement in the project.
