Mrs. Carmody is a middle-aged townswoman with a reputation as a witch. She is known in Bridgton for her mental instability and her bloodthirsty belief in a vicious God. She serves as the main antagonist of both the novella, The Mist, and the film adaption.
She is one of the patrons trapped in the Grocery Store when the Mist appears and engulfs the town outside, and is convinced that the Mist is a punishment from God for mankind's sin and dissolution; particularly after David and Ollie explain their encounter with the Tentacles from Planet X in the storage room.
Mrs. Carmody attempts to convince the other market patrons that the Mist is a divine punishment, but is stopped when she is hit her across the face and threatened by Ollie. However, Mrs. Carmody shows no fear of Ollie's threat, and predicts that the creatures in the Mist will claim another victim at night.
Instead of being weakened by the siege mentality caused by the Mist, Mrs. Carmody is strengthened by it, and by the second day, she successfully gains a small group of followers, driven mad by the trauma of the phenomenon, which quickly grows into a congregation.
On the morning of the third day of the disaster, Mrs. Carmody attempts to sabotage David's group from escaping the market by destroying the supplies they gathered, and then orders her followers to first sacrifice Billy and Amanda, and then to massacre David's entire group. However, she is shot by Ollie and killed.
Mrs. Carmody's death led to the breakup of her congregation, and nearly all of the people who she had brainwashed were snapped back to reality after they realized all that they had done, and the fact that her death showed that she did not have divine protection as she had preached.
Differences Between the Novella and Film
- In the film, while Mrs. Carmody was praying in the store bathroom, she spitefully turned down Amanda's attempts to comfort and befriend her.
- In the novella, an unnamed man hits and silences Mrs. Carmody, whereas in the film, it is Amanda Dumfries.
- In the film, when Private Jessup reveals what he knows about the Arrowhead Project, Mrs. Carmody and her followers insanely sacrifice him by locking him out of the store to be killed by an Arachni-Lobster.
- In the novella, Mrs. Carmody is only shot once, in the abdomen, and with her dying breaths, she warns David and his group they they will die out there. In the film, Ollie shoots Mrs. Carmody once in the stomach, then finishes her off with a shot to the head. In the movie script, Ollie intended to shoot her only one time, but as David and his group were passing her by, she managed to yell out an order to kill David's group again, causing Ollie to immediately shoot her again.
Amanda initially tried to befriend Mrs. Carmody, but Mrs. Carmody spitefully turned her kindness down, saying that if she "wanted a friend like her, she would squat over and [poop] one out". Later, when Amanda hit Mrs. Carmody to shut her up, Mrs. Carmody darkly threatened her in response. She later tried to sacrifice Amanda, but was stopped when Ollie killed her.
In the book Carmody somehow learns of David and Amanda's affair, and refers to her as a "whore" for the remainder of the book. In the film, this subplot is omitted.
Irene deeply hated Mrs. Carmody and was not afraid to show it. When Irene stoned Mrs. Carmody in the middle of a preaching with a can of peas, Mrs. Carmody tried to attack Irene in a fit of anger. Mrs. Carmody later tried to have Irene sacrificed, but was killed before it could be done.
Initially, Jim drunkenly mocked Mrs. Carmody for her fanatic beliefs, and was quick to threaten her. However, after Jim became one of her followers, he only became calm when she soothed and spoke to him. Her death made him snap back to reality.
