Carrigan Crittenden is the main antagonist of the 1995 live-action movie adaptation of Casper. She is a glamorous, treacherous, and greedy heiress who discovers that Whipstaff Manor contains treasure, and seeks to obtain it so that she can become rich, while also planning to get rid of Casper and the other ghosts that are inside the house, which is theirs.
She was both portrayed and voiced (in her ghost form) by Cathy Moriarty.
