A longer view of history would not change our expectations. Actors and actresses have historically had a reputation of very low morals. I'll skip over recent history to a more ancient time.
Remember that the Greek word for actors is ὑποκριταί, whence the English hypocrite. When Jesus wanted to insult the Pharisees, he called them actors (Matthew 23). This is an insult on several levels:
- Actors pretend to be something that they are not. They do one thing on stage (or screen) and another in private life. This is the hypocrite theme that Jesus stresses in his specific examples. One way to look at the profession is that an actor is a professional hypocrite.
- Actors had a reputation, even then, of low morals, while the Pharisees cultivated a reputation of high morals.
- Actors and the theater were largely used in plays promoted by Gentiles. The Pharisees saw themselves as being anti-Gentile.
