Don't really know anyone famous but I've worked with a few people responsible for some pretty famous stuff. I was VFX supervisor for a commercial shoot in LA a couple of years ago which had a crazy crew. The director of photography had an Oscar from "Memoirs of a Geisha" (an Aussie by the name of Dion Beebe), the 2nd AD was 2nd unit director on "Ronin" and basically everyone on that job had done some pretty big jobs.
My favorite though was the script supervisor who had worked with Spielberg for the last 20 years and showed me a photo of her, in her younger days, on the set of "Blade Runner"!!
Fortunately my job involved sitting next to her for most of the 2 week shoot listening to her crazy stories
I've been on shoots with a few big actors too but I'm not really into celebrity and prefer those that have earned their status behind the camera (or computer as it often is).
