The music that plays during Mickey and Pete's duel and during the ending was later used in Thru the Mirror.
A clip of Mickey and Pete's duel was used for the scene of Goofy pardoning other people while he's watching in the theater in the Disneyland episode "The Goofy Success Story".
This short appears in Epic Mickey as one of the projector levels.
Minnie's screaming and Pete's evil laughter were later reused for Get A Horse!
