* ActorAllusion: Dana Delany delivers the line "He laughs!" exactly as she did in ''{{Film/Tombstone}}''.
** While it's purely casual, in the Finnish dub Joker says that the Phantom looks like [[Franchise/StarWars Darth Vader]]. Coincidence ?
* HeyItsThatVoice: The woman at the party who shouts, "Brucie, where are you?" off camera is Arleen Sorkin, voice of ComicBook/HarleyQuinn.
** Salvatore Valestra is voiced by [[Film/TheGodfather Abe Vigoda.]]
** Andrea's VA, Dana Delany, would go on to play Lois Lane in ''WesternAnimation/SupermanTheAnimatedSeries''. Indeed, it was this performance that got her the role of Lois Lane.
** Chuckie Sol is voiced by Dick Miller, a regular in films directed by Creator/RogerCorman and Creator/JoeDante.
* RealitySubtext: Andrea is named after Andrea Romano, the voice casting director for the series. The entire romance plot came about because of Creator/KevinConroy ad-libbing an "Oh! Andrea" after a series of grunts. It was originally intended to be Batman getting punched, but the ad-lib made it sound [[ImmodestOrgasm a little different]].
* The fighting style Bruce was shown practicing was very close to Taekwondo, despite him calling it "Jui Jitsu". The move Andrea performed on him, however, ''was'' from Jui Jitsu.
