Fernando Montealegre was among the first staffers at Hanna-Barbera, jumping over from MGM where he started as an assistant animator and became a background artist. In keeping with the times, his work on Mike Lah’s Droopy shorts (in Cinemascope) at MGM are quite stylised.
The Mickey Mouse short The Whoopee Party (1932) has a lot of cycle animation dancing, and Uncle Walt manages to fill the screen with the left side being the mirror animation of the right side.
Friz Freleng, by all accounts (mainly his), did not enjoy working on the Captain and the Kids series at MGM. But someone did, judging by one scene in A Day at the Beach (1938).
Fred Allen returned to the airwaves on October 7, 1945 after a year away for health reasons. Newspaper stories mentioned a change in Allen’s Alley, but omitted the most significant change of all.
For years, the Jack Benny show, on both radio and TV, featured a routine where Jack and his gang took a train from a station where he was verbally harassed.
When you think of a cartoon where a character comments on the action, another character talks to the audience and another character holds up a sign, you probably think of Tex Avery. He wasn't the only one.
Jack Benny was a hit wherever he went. Despite being on radio and TV in the first half of the 1950s, he was able to get away to appear with his act in public.
