Actors read lines and change their facial expressions. Even then they usually need a director to tell them how to do it. It could be argued that actors are not creators or are at best secondary creators. Actors create something from something, usually a prewritten script. Whereas sculptors will create something from the raw material of the earth only using their hands and no other tools. In this regard sculptors are higher creators than painters, and painters are higher creators than musicians or writers who use symbols and tools to create. Actors however are the lowest of all creators. Perhaps that helps to explain why Hitchcock said, “Actors should be treated as cattle."
