It sounded like a simple idea for a spot... lower a sign in the background, then dump a bucket of confetti on an anchor. Easy!
Then comes the logistics: What's the sign attached to? Who will lower it, and from where? Can we power the lights on it? How do we dump confetti straight down in a wide shot? Can we keep the bucket out of the shot? What if we miss? Where are we going to get all that confetti?!
Working out all the details and rigging everything perfectly required about two hours and six people... but it worked! Eureka! Check it out:
I won't reveal just how we did it, but I will say next time we should just do it all in post.
