OK so I'm not necessarily brand new to the industry but I've been working for a few years. I've only gotten PA or 3rd AD roles up until this point. I'm now getting ready to work on a production as a 4th AD and I'm not really sure what that means as far as things I'm expected to do. Google gives me a few different anwsers (Key PA, Trailer AD etc) but was wondering if anyone with experience could detail it to me a bit better TIA!
