Fun and Fancy Free
Disney had provided the voice for Mickey Mouse since his debut in 1928, and "Fun and Fancy Free" was the last time he would voice the role regularly, as he no longer had the time or energy to do so. Disney recorded most of Mickey's dialogue in the spring and summer of 1941. Sound effects artist Jimmy MacDonald would become the character's new voice actor, starting in 1948. Disney, however, did reprise the role for the introduction to the original 1955–59 run of "The Mickey Mouse Club".
Mickey Mouse universe
Shyster disappeared for a time after 1934, but made comebacks in 1942, 1950 and again in various 1960s Italian-created stories. More recently, publisher Egmont Creative A/S (in Denmark) revived Shyster as a regular character, a capacity in which he continues today.
The Sleuth, Sureluck Sleuth in full, is an anthropomorphic canine. He is an English private eye operating in 19th century London and employing Mickey Mouse as an assistant. The character was created by Carl Fallberg (plot) and Al Hubbard (art) for the Disney Studio Program and intended solely for foreign publication. The first story in the series is ""Mickey and the Sleuth: The Case of the Wax Dummy"". Unusually for material created for the program this story appeared domestically in the Procter & Gamble "Disney Magazine" giveaway and then was published by Gold Key in ""Walt Disney Showcase"" n°38 (1977). Given their historical setting, the ""Mickey and the Sleuth"" stories stand apart from other Mickey Mouse continuities. It is never explained if the "Mickey Mouse" working with the Sleuth is an ancestor of the present-day Mickey or if those stories are to be included in a totally different continuity. Apart from Mickey, no other prominent Disney characters are featured in the stories.
