Inside Magoo (1960)

A public-service announcement from the American Cancer Society featuring Mr. Magoo. Not part of the regular series, this rare cartoon begins with a bunch of clips talking about the history of the movies, then has some discussion about how Magoo is made, and a talk with Jim Backus. Then the bulk of the film is a Mr. Magoo cartoon featuring Magoo learning about cancer danger signs and how to protect yourself.

Unfortunately the movie Inside Magoo is not yet available on HBO Max.
