So so true....A friend and I used to be into film acting (commercials and indie films) in our early 20's and we saw a lot of crazy stuff.
Guys pretending to be directors borrowing nice equipment and seeing just how many nude shots they could get from desperate girls wanting to break into the acting business..it was disgusting.
I even know a couple guys that say they were almost gang raped by men that actually were film directors. You definitely can't be too careful in that business.
A good agent you can trust = worth its weight in gold.
