* [[ActingForTwo Acting for At Least 10]]: Every female in this series was voiced by Peg Dixon. She'd go on to do the exact same thing (while mainly voicing Betty Brant) in ''WesternAnimation/SpiderMan1967''.
* FakeNationality: The fact that this show was produced in Canada, and most of the comics starred Americans, created plenty of examples.
* FakeRussian: The voice actress of Comicbook/BlackWidow.
* HeyItsThatVoice: Paul Soles (Bruce Banner, Rick Jones, Happy Hogan) would later voice [[WesternAnimation/SpiderMan1967 Spider-Man]].
* KeepCirculatingTheTapes: Creator/{{Disney}} has owned TV and home video rights for even longer than they've owned Creator/MarvelComics itself, but plans to release the shorts on DVD and Netflix became inexplicably delayed, bar some of the Hulk's shorts showing up on a DVD of his 1990s cartoon. The UK and Canada have some official DVD sets.
* TheOtherDarrin: {{Hawkeye}} originally had Chris Wiggins as a voice actor, but Paul Soles later replaced him.
* TalkingToHimself: Paul Soles voiced both Bruce Banner and Rick Jones (this also counts as DawsonCasting).
