I don't say much about what I know, saw and dealt with because it can sound like gossip and name dropping (and BS). I liked working on the defense side because I genuinely like people. The stalkers freaked me out worse than the gossip and rehab stuff because stalkers are unpredictable and numerous. People have no idea what celebs put up with, especially young female stars, because rule #1 is "Don't ever mention your stalkers." It just makes them worse. Celebs aren't allowed to complain about fame and all the unseen crap that comes with it because "they asked for it"
I was born into the business and there are many good people in it but the bigger dynamic is vapid sensationalism and distortion of reality. It attracts borderline personalities and delusional people. My mother was working as an actress when I was born. By age 4 I was going with her to gigs and auditions mostly to keep the producers from hitting on her (or worse). We had a hand signal worked out for me to interrupt whatever was happening. Her career ended. During college my own career began. I was Assistant Script Supervisor and stuntman on a TV stunt show that shot at Sunset Gower. Inside those 20-foot walls it was business but right outside on the sidewalks it was hell on earth. Eventually I moved to NYC where it is much more sedate and sane.
There is a saying among the famous -- "Fame is like a tiger that comes to your door every day and the day you have nothing left to feed it, it eats you."
I have nothing but respect for those who don't get eaten.
