* ActressAllusion: Bette Midler (voice of Georgette) currently has a New York City apartment at 1125 Fifth Avenue, so she has same address as her character and probably lived there when the movie was made (unless it's an astounding example of LifeImitatesArt).
* ChannelHop: In North America, this film has always been with Disney; however, in most international territories, it was originally released in theatres by Creator/WarnerBros, and in other international territories this was handled by United International Pictures. This is due to output deals Disney made for international theatrical distribution.
* DuelingMovies: The 1980s was a very tumultuous time in animation. Creator/DonBluth had very publicly split with Disney and started his own studio, which naturally was in competition with Disney. ''Oliver'' had ''two'' rivals from Bluth: ''WesternAnimation/TheLandBeforeTime'', which came out on the same day; and ''WesternAnimation/AllDogsGoToHeaven'', released the following year but also featuring a roguish talking dog and a heartwarming little girl. ''Oliver'' did better than either in theaters (though "Time" had the higher opening weekend and worldwide gross), though it's now a somewhat forgotten member of the Disney canon while ''The Land Before Time'' and ''All Dogs Go To Heaven'' went on to spawn long-running video franchises.

* HeyItsThatVoice: Several examples. To name a few...
** Music/BillyJoel as Dodger. Seriously.
** Creator/DomDeLuise as Fagin.
** Bette Midler as Georgette.
** [[Series/{{Blossom}} Joey]] [[Series/GimmeABreak Lawr]][[Series/MelissaAndJoey ence]] as Oliver.
** [[Creator/CheechAndChong Cheech Marin]] (AKA [[Disney/TheLionKing Banzai]] and [[WesternAnimation/{{Cars}} Ramone]]) as Tito ([[PigeonholedVoiceActor fittingly]]).
** Robert Loggia as Sykes.
** Sheryl Lee Ralph, the original Broadway Deena Jones in ''Theatre/{{Dreamgirls}}'', as Rita's speaking voice, with Ruth Pointer, one of the Pointer Sisters, as Rita's singing voice.
** Richard Mulligan, mostly remembered from ''{{Soap}}'' and ''Series/EmptyNest'', as Einstein.
*** Apparently in the German dub, Fagin either lives in [[{{Disney/TheJungleBook}} a temple ruin]] or [[SpongebobSquarepants a tiki head under the sea.]]
* WhatCouldHaveBeen: Originally this movie was going to be a pseudo-sequel/spinoff of ''Disney/TheRescuers'' that followed Penny after she was adopted. You can still see some traces of it. (namely the main character's name being changed to "Jenny").
