Don't know if this is what you are thinking of... it is only available via mail, it is printed on dark red paper so it cannot be photocopied and is expensive, it is called Professional Casting Review. I used to get when I was working as a film extra.
Film extra work often invloves long boring hours sitting around until they need you! Most have two jobs and take a laptop with them these days and work on that while waiting. The pay varies wildly but IF you get to say a few words the pay rises dramtically, adverts are good though.
