Charlie's Haunt

Edgar Bergen (playing himself) goes to meet up with Richard Travis (playing an executive of a local telephone company) so they can go on a fishing trip. But first Travis goes to visit a worker who was injured in an accident. All day long at work, he goes up and down ladders, and does so in a measured way. At home, he gets careless, and crash! Two broken legs, and his daughter has a broken collarbone too. So Bergen's sidekicks (Charlie McCarthy, Mortimer Snerd, et al.) become disembodied voices hectoring people to be as careful off the job as they are on the job.

It's an industrial film produced for AT&T, intended to get their employees to behave safely. The copy I looked at was intended for class rooms.

It's hard to understand the popularity of Edgar Bergen's act. Although he started in vaudeville, and made a dozen and a half short films doing his act, he achieved his greatest success on the radio, where his artistry with switching voices couldn't be seen.
