Mirai Shounen Conan (Movie) is a summarized version of the television series, but made without the involvement of the series' director Hayao Miyazaki. Due to significant changes made to adapt the story into a two-hour movie and the use of a different soundtrack, the result was not well-received by fans. To promote the film, a "Conan Festival" was held at Nippon Budokan on July 20, 1979. Nippon Broadcasting System ran a four-hour live broadcast during its All Night Nippon program on August 31, 1979, featuring a live radio drama of the film with a newly written script. The voice actors also made guest appearances and interacted with fans by phone. On August 8, 2012, Mirai Shounen Conan (Movie) was aired on NHK BS Premium as one of the Summer Vacation Anime Specials. For this purpose, it was digitally remastered.
