The Daicon III and IV Opening Animations are two 8 mm film anime short films that were produced for the 1981 Daicon III and 1983 Daicon IV Nihon SF Taikai conventions. They were produced by a group of amateur animators known as Daicon Film, who would later go on to form the animation studio Gainax. The films are known for their unusually high production values for amateur works and for including numerous references to otaku culture, as well as its unauthorized appropriations of the Playboy Bunny costume. Usage of the songs "Runaway" by Bill Conti (from the soundtrack to the 1981 James Bond film For Your Eyes Only) as well as "Twilight" and "Hold On Tight" by English rock band Electric Light Orchestra were also unauthorized.
Daicon III was made by Hideaki Anno, Hiroyuki Yamaga and Takami Akai and Daicon IV credits twelve people, including Yamaga as the director and Anno and Akai as animation supervisors. Despite the questionable legal status of the works, the production of Daicon III resulted in debts that were repaid by selling video tapes and 8 mm reels of the production, the profits of which went to the production of Daicon IV. In 2001, the anime magazine Animage ranked the Daicon animations as the 35th of the "Top 100" anime of all time.
