The flying ghost girl, Aimee, had been shot underwater in slow motion against a green screen. The pool wasn’t entirely clean, so there were tiny pieces of debris everywhere that had to be removed. Cleaning up the green screen around the girl’s hair was also challenging (as cleaning around hair usually is). The biggest task here, though, was addressing the bubbles coming out of Aimee’s nose and mouth, especially when she screams. On set, those bubbles crossed in front of her face on numerous occasions. This meant that we weren’t just cleaning things up. Pieces of her face and even her teeth had to be repainted in every frame where a bubble was interfering.
