Maybe I'm being overly cautious. But just some risks to consider if you're gonna try this for the purposes of getting a look behind the scenes: Some film sets with union folks can get very particular about who touches what. But maybe the things you'd help carry wouldn't fall under the responsibility of said union folks. Also, if a film set has had a robbery or theft, and the crew has worked with each other long enough to know who the regular day players are, you'd stick out like a sore thumb. But all these types of chicanery will come with such risks, I suppose.
