Cast the Expert: Ratchet Altair, an American stage actress/singer, is played by real-life actress/singer Akiko Kuno.
Celebrity Voice Actor: Curiously enough and unlike Tengai Makyou (who used many celebrities in the voice acting), there's only one voice actress who is not a bonafide professional one: Akiko Kuno (Ratchet Altair's VA), whose career as a professional theater actress and singer dates all the way back to 1972. Taking into account Ratchet is also a stage actress, Kuno's actually a natural fit for that role.
Irony as She Is Cast: Sakura Shinguji speaks much worse English than her voice actress, Chisa Yokoyama, who actually took a 15-week English course in Australia back in 1994.
Keep Circulating the Tapes: Geneon Entertainment's North American rights to the film expired after they shut down in 2007, meaning that some of the extras that were included in the release such as the art book and pencil boards are hard to find. Fortunately, the film was picked up by Funimation, who released it in both physical and digital formats in 2013.
Marth Debuted in "Smash Bros.": This movie, at 2003, was the very first animated adaptation of the franchise dubbed in Spain, since the previous adaptations didn't get released there until 2006, when the OVAs were also brought to that country. This is in a very stark contrast with Latin America, when the TV series and OVAs were dubbed, but not the movie.
The Other Darrin: None of the original English actors of the OVAs and TV series reprised their roles. The movie was recorded at Bang Zoom! Entertainment in Burbank, California, instead of Austin, Texas.
Playing Against Type: Mona Marshall voiced Reni (who is female) back when she was still primarily portraying young boys, though the character still does look like a young boy at first glance.
Production Posse: In addition to Mika Akitaka, Satoru Akahori, Kohei Tanaka and Oji Hiroi, the film features several regulars from the Sakura Wars series as well as those from Production I.G.
This was Mitsuru Hongo's first assignment with Production I.G as director, but he would also perform similar duties on IGPX: Immortal Grand Prix.
Toshihiko Nakajima, who played a member of the Elder's Institute, previously provided minor roles in the Sakura Wars TV series as well as playing the oyakata in the stage musicals.
From The Iron Giant: Yokihiko Ota is the Iron Giant, Yoritsune Hanakoji (Koichi Kitamura) is Earl Stutz, and Ikki Yoneda (Masaru Ikeda) is General Shannon Rogard.
To keep in line with Hiroi's request to cast actors/actresses with experience in voice-over, singing and stage work, Shintarō Sonooka (Kōsuke Dan in the musicals and second OVA) personally suggested Akiko Kuno, who worked with Sonooka in the past, to voice Ratchet.
Role Reprise: Several voice actors reprised their roles as the characters that they portrayed in the games, including Chisa Yokoyama as Sakura Shinguji and Akio Suyama as Ichiro Ogami. Not to mention Yūji Mitsuya returning as Musei Edogawa from the stage plays.
The film was the first Sakura Wars anime not to be produced by Radix, with the animation instead being handled by Production I.G.
Geneon licensed the film for a North American release instead of ADV Films (who distributed the first two OVAs as well as the TV series) in 2002. The film was eventually picked up by Funimation (who rescued many series formerly licensed by Geneon) in June 2013, giving the company a piece of Sakura Wars history once more.
As for the Japanese home media releases, they were originally handled by King Records, before switching to Kadokawa Shoten in 2013.
What Could Have Been: Oji Hiroi originally envisioned that the film would be similar to the FMV sequences in Is Paris Burning?, but Production I.G nixed it due to resource management becoming impractical.
