2002 movie
"This isn´t over. This is far from over" - Chris to the girls

Chris "Christine" Hargensen was portrayed by Emilie de Ravin and was more similar to the "novel" Chris than Nancy Allen's version, showing more characteristics. She is the leader of a group of popular girls called The Ultras. At one point she even tried to convince Carrie that Sue was the "enemy." , thus, making her an evil character. In this film, Chris is presented as a cruel, wicked and manipulative girl, who also bullied other students. However, she does have some remorse in herself.

Christine was first introduced in the movie, annoyed because of Carrie missing the ball. When Tina notices Carrie having her period, she tells Chris and she throws tampons at her along with the rest of the Ultras. Later, after Chris was banned from the prom because of testing Ms. Desjardin and saying that she won't take place in detention, her father, the "big-time lawyer" John Hargensen (Mchael Kopsa) threatened to have the gym teacher fired and take the school to court, if Christine's prom privileges were not restored. Principal Morton, however, did not cave in, and countered by saying that he would battle Hargensen's suit on all fronts. He further stated that Christine belonged in either military school or jail for her countless acts of cruelty against the "reject" student population. Her father, realizing he would lose, relented and she was out of prom officially.

Because of all of this she plans her vengeance on Carrie, but unlike the other versions, however, Christine is shown having a certain tendency of changing her heart, when she saw, how happy Carrie was at the prom and was reluctant to drench pig's blood over Carrie, but her boyfriend and accomplice Billy pressured her to do so and she gave in. The evil prank succeeds, causing Tommy's death on the way. Later they celebrated it, until they heard about Carrie's murderous rampage and returned to Chamberlain.

Finally, when they found Carrie on the street, Billy tries to run her over with Christine's half-pleas for him to stop. Still she doesn't stop him either and it is finally Carrie, who stops the car and sends it smashing into a tree, killing and crushing both Billy and Christine on the way like a ground mutton. Carrie hallucinates about her after the Black Prom massacre.
