This allowed for the space opera Space Battleship Yamato (1974) to be revived as a theatrical film. Mobile Suit Gundam (1979) was also successful and revived as a theatrical film in 1982. The success of the theatrical versions of Yamato and Gundam is seen as the beginning of the anime boom of the 1980s, and of "Japanese Cinema's Second Golden Age". A subculture in Japan, whose members later called themselves otaku, began to develop around animation magazines such as Animage and Newtype. These magazines formed in response to the overwhelming fandom that developed around shows such as Yamato and Gundam in the late 1970s and early 1980s. In the United States, the popularity of Star Wars had a similar, though much smaller, effect on the development of anime. Gatchaman was reworked and edited into Battle of the Planets in 1978 and again as G-Force in 1986. Space Battleship Yamato was reworked and edited into Star Blazers in 1979. The Macross series began with The Super Dimension Fortress Macross (1982), which was adapted into English as the first arc of Robotech (1985), which was created from three separate anime titles: The Super Dimension Fortress Macross, Super Dimension Cavalry Southern Cross and Genesis Climber Mospeada. The sequel to Mobile Suit Gundam, Mobile Suit Zeta Gundam (1985), became the most successful real robot space opera in Japan, where it managed an average television rating of 6.6% and a peak of 11.7%. The otaku subculture became more pronounced with Mamoru Oshii's adaptation of Rumiko Takahashi's popular manga Urusei Yatsura (1981). Yatsura made Takahashi a household name and Oshii would break away from fan culture and take a more auteuristic approach with his 1984 film Urusei Yatsura 2: Beautiful Dreamer. This break with the otaku subculture would allow Oshii to experiment further. The otaku subculture had some effect on people who were entering the industry around this time. The most famous of these people were the amateur production group Daicon Films which would become Gainax. Gainax began by making films for the Daicon science fiction conventions and were so popular in the otaku community that they were given a chance to helm the biggest-budgeted anime film (at that time), Royal Space Force: The Wings of Honnêamise (1987). One of the most-influential anime of all time, Nausicaä of the Valley of the Wind (1984), was made during this period. The film gave extra prestige to anime
