* TheOtherDarrin: "A Day for Eeyore" is the first theatrical ''Pooh'' cartoon to feature replacement voices for Pooh (Hal Smith), Rabbit (Will Ryan[[note]]Who would voice both him and Tigger in Welcome to Pooh Corner.[[/note]]), Kanga (Julie [=McWhirter=]), and the Narrator (Laurie Main[[note]]Who would also appear in Welcome to Pooh Corner also playing the narrator (both off screen and on screen).[[/note]]). Roo and Christopher Robin, who had already been portrayed by multiple voice actors, are also recast here.
* TalkingToHimself: Hal Smith does double duty in "...and a Day for Eeyore", taking over the role of Pooh while also retaining his established role as Owl.
* WhatCouldHaveBeen: Creator/WaltDisney had tapped famous Disneyland performer Wally Boag to voice Tigger in ''Blustery Day'', and Boag contributed heavily early on in the short's development to help define Tigger's personality. After Disney's death, Boag was dropped from the project in favor of Creator/PaulWinchell. Other actors who auditioned for the role included such legends as Creator/PaulFrees, Creator/DonMessick, and Creator/DawsButler.
