* AlternateCharacterInterpretation: Fujiko. Depending on which part of the fanbase you ask, she's either:
** A [[FemmeFatale steamy seductress]], who uses her feminine wiles and her body to play Lupin like a fiddle, while retaining her street smarts and ActionGirl status - complete with a BigDamnHeroes moment.
** Or, [[TheyChangedItNowItSucks she's nothing like]] [[ClassyCatBurglar the Fujiko they've come to know and love]]. Instead, she's a skank who sleeps with Lupin because she can't find [[TheCaper a job]] of her own, and is reduced to being nothing but MsFanservice.
* BrokenBase: ''Secret of Twilight Gemini'' is a LoveItOrHateIt type deal for varying reasons:
** The most common criticism is [[DependingOnTheWriter the way it portrays Fujiko]]. Newer fans who are used to her being a ClassyCatBurglar, who is witty and Lupin's equal, didn't take kindly to ''Twilight Gemini's'' portrayal of her as [[MsFanservice promiscuous]] and [[SexyDiscretionShot sleeping]] [[SexWithTheEx with Lupin]] to persuade him to let her in for a cut of the treasure he's after.
*** The irony of their complaints is that Fujiko's characterization here is actually closer to the way she was originally portrayed in the manga. Even more ironic when ''[[Anime/LupinIIITheWomanCalledFujikoMine The Woman Called Fujiko Mine]]'' seems to go for more of a middle ground between the two portrayals, though minus the sex with Lupin.
** Others simply didn't appreciate the sheer amount of nudity and {{fanservice}} present in the film, even though Funimation released a censored version that [[DeletedScene removes these elements altogether]].
** And [[TakeAThirdOption for some]] it's a case of SoOkayItsAverage when compared to the other films in the series; most notably, ''Anime/TheCastleOfCagliostro''.

* GeniusBonus: Dalune is an alias for Arsene Lupin the First. [[KissingCousins Lupin and Lara are cousins.]] It also adds a great deal of meaning as to why Lupin is so interested in helping these locals out.
