White Chicks - Disappearing Contacts
In the end sequence when Marlon Wayans' character is comforting the guy who got shot trying to protect Marlon's character, the guy is telling Marlon how he had to save his lady love. Marlon's character takes off his mask to show he is a man and in doing so his blue eyes turned to brown. Were the contacts made into the face mask? The same thing happened when Marlon's character's wife snatched off Shawn's mask. Both of their eyes returned to brown from blue just by snatching off the mask.
