Okay, I’m not talking about portal-to-portal: what’s the longest you’ve spent, on the clock, working on a set in one day?
I had some friends on the SNL film unit talk about a hellscape of 18 hours, but I know they mostly do two separate crews with separate shifts if they can staff it.
My personal record is 16.75 hours, sadly on a union majors movie. That was a lucrative but horrible day.
I’ve done the 16 hour day for a music video I was directing. Low pay, but tons of fun. Wouldn’t do it again though. I try to plan my shoots out much better now.
