* 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 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.
** [[{{Blossom}} Joey Lawrence]] 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").
