"A movie and a stage show are two entirely different things. A picture, you can do anything you want. Change it, cut out a scene, put in a scene, take a scene out. They don't do that on stage"

In this quote, Cab Calloway is highlighting the stark differences between motion pictures and performance. He emphasizes that with a film, there is a lot more liberty to control the story and visuals. Scenes can be added or gotten rid of, and the total picture can be become fit the director's vision. However, on phase, this is not possible. The efficiency is live and there is no space for editing or altering the story. This highlights the distinct and dynamic nature of performance, where the stars should count on their skills and the audience's responses to create a memorable efficiency.
