Sure thing, kid. Grab a bottle of water, not a fancy smoothie, and let everyone take a slow inhale—no more than five seconds—then a deep exhale. Keep your voice low, make it a ritual: “Breathe in, breathe out.” It’s the same as telling a stunt to hold his breath before the big jump. That steady rhythm takes the adrenaline off the set, keeps the crew from snapping like a cheap prop. And remember, a crew that’s breathing together doesn’t care how many flashes of the light go off. Stick to that and nobody will blow up anything, either on the screen or off it.
