Not sure about Rodg.... they did use the lot for locations frequently. There's a pretty good introduction to the lot here: http://wbsf.warnerbros.com/indexvipredir.html
(check the links on the left) That VIP tour of theirs is one of the town's undiscovered gems. It doesn't have the entertainment value of the Universal tour, but for folks who really want to see a studio lot close up, it's a good opportunity.
I sure agree with your comments about the suits. At the end of my career, we'd tripled the number of people 'supervising' us with no net increase in the number of people actually doing the work. My work load had increased, though, because I had to spend a lot of time undoing the problems the 'suits' were creating.
One particular gal kept trying to ship the stock shots I was using for the whole season back to the supplier. It made no sense at all, since it cost us nothing to keep them. I finally issued an edict to the vault to run any order she gave by me first. For the rest of the season, at two week intervals, she'd order them shipped and I'd cancel the order. Strangely, it never seemed to occur to her to ask why her order hadn't been carried out.
Then there was the 'post production supervisor' who kept ordering copies of the finished show before we'd finished it.....
Did I mention I'm glad I retired?
What show were you working on, if you can say?
