In the scene where Leeloo has just come out of the air ducts in the lab, and the police have her backed up against the wall of the building, Leeloo raises her hands in the air when the police asks her to. Here, her hands are black with dirt and dust from the floor of the air ducts. Then, Leeloo jumps in the air and lands in Korben's cab. When Korben stops the cab, he asks, "Any survivors?" Then, Leeloo puts her hand up on the window between her and Korben. Her hand here is clean! The dirt and dust are almost completely gone!
