When I was a young teen, Ralph Waite, the father on the Waltons and also a pastor gave a talk at a nearby church about the dangers of letting your children work in Hollywood. That was over 40 years ago.
Many years ago I had a very good teacher who had been a child actor. Without going into details he would hint darkly that as an attractive child he had been very much an ideal target for certain types of individuals who were quite common in his profession.
Will Geer was on the Waltons with him. He was a commie and liked guys.
