Kawamori and Matsuzaki had originally designed an elaborate ending sequence for the film, which would have featured Minmay singing "Angel's Paints" while we caught glimpses of the other characters watching the concert. This sequence (and a storyboarded sequence featuring Max and Millia's wedding) were scrapped due to the budget running out. The concert sequence was later animated in Chôjikû yôsai makurosu furasshubakku 2012 (1987) and the concert sequence was finally appended to the end of Macross DYRL to complete the film as the creators had intended.
According to Kawamori, this film is considered a "fictional film" within the Macross universe, that was made some years after the events depicted in the TV series. This explains the major differences between the designs in the TV series and the movie. He has also at some points left it up to viewer interpretation to determine which is the "real" version of events.
After the climatic final battle, Minmay is holding up the Lyrics to the song to show Misa and Hikaru. If you look closely you'll notice the lyrics are in English, even though she sang them in Japanese.
When Minmay and Hikaru are running through Macross City, one of the billboards is actually a bumper sticker for the San Francisco radio station KMEL. While Kawamori was in SF, he became a avid listener of the station.
This movie has become caught up in numerous legal disputes on both sides of the Pacific (the most prominent, although by no means only one being the copyright dispute between Big West/Studio Nue and Tatsunoko/Harmony Gold), and it has been said because of this, there might never be a legitimate United States release of the film on DVD.
In the TV series the Zentraedi's dialouge was automatically translated into Japanese. Here they speak an actual made-up language and subtitles are provided for the audience. Much like Klingon in Star Trek, of which a word wasn't spoken until they appeared in the first movie.
