65th Academy Awards
There was a minor controversy when Snow White (Disney character) was presenting an award for Best Animated Short Subject. She was voiced by Mary Kay Bergman, Adriana Caselotti, the original voice of Snow White was not aware of this. She was reportedly offended that Disney didn't ask her to voice Snow White during the ceremony.
Bill Thompson (voice actor)
For Walt Disney Studios, he was heard in many shorts and features, often in either dialect parts or a variation of his Wimple/Droopy voice. His animated feature film credits included the parts of the White Rabbit and the Dodo in "Alice in Wonderland", Mr. Smee and the other pirates in "Peter Pan" (reprising his roles in radio adaptations for "Lux Radio Theater"), and King Hubert in "Sleeping Beauty". Many of the characters he played in Disney productions are now voiced by Corey Burton and Jeff Bennett.
