Deliberately lying to the actors, and then making them sign contracts for something that did not exist?
A first year law student could get the original contract nullified in a couple of minutes.
There was a a startup, think around the year 2000, that would hire people, but wouldn't tell them the name of the company, or what they were doing, and they couldn't tell anyone where they were working. It might have been called Epinions.
As for lying and egotistical misconduct by and among actors, producers, directors, and studio executives, they are common if disliked for obvious reasons. Yet they are so much a part of the business of Hollywood that movies are made about the often malign effects on the people involved. Some of those movies are quite good, like The Bad and the Beautiful, The Last of Sheila, Sunset Boulevard, White Hunter, Black Heart, Whatever Happened to Baby Jane?, and others.
The general sense of Hollywood's view of itself is that yeah, lying and self-centered misbehavior are bad, but that is how things work -- and what do you expect of a business built on acting -- which, after all, is itself a form of lying?
