A life tip from Gerard Butler: Don’t rub phosphoric acid on your face. The actor found that out the hard way when he accidentally wiped the substance on his visage while filming a climatic scene for Plane.
Appearing on Late Night with Seth Meyers (via EW), Butler explained how the accident happened while shooting Plane in Puerto Rico. His character, Brodie Torrance, goes hands on to fix an aircraft’s faulty brakes.
“Now I’m sticking my hand in between these two wheels, kind of pretending that I know what I’m doing,” Butler told Meyers. “Every time I bring my hands out, they’re covered in blood and green fluid, right? And I’m like, ‘I don’t know what this green fluid is.'”
