Curtain Razor (1949)

Continuity mistake: When the turtle comes in saying he is known as "The Man with 1000 Voices", look at Porky. You can see that the drawer in the filing cabinet behind him is closed and he is sitting directly in front of it, but after the turtle has finished his audition, the filing cabinet has moved a few inches away to the left and the drawer is now open.

Trivia: One of the acts auditioning is a turtle who says he is "The Man of 1000 Voices." This was the nickname of the Warner Brothers voice actor, Mel Blanc.
