Callie Chalmers (Charisma Carpenter) was the main villainess of the 2011 Lifetime film Deadly Sibling Rivalry (airdate August 15, 2011). She was the evil twin sister of main protagonist Janna Chalmers (also played by Carpenter in a dual role). Growing up, Callie and Janna had a contentious rivalry, with the former expressing immense jealousy of the latter. As a teenager, Callie's resentment became pure hatred, and 20 years prior to the film's events, she attempted to murder Janna. While they were preparing to go rock climbing with their father Henry, the villainess slightly cut her sister's harness so that it would snap during the climb. However, it was their father who ended up using the sabotaged harness, and he plunged to his demise after said harness broke. Callie callously blamed Janna for the murder (despite the former being the murderer herself), and since then, she lived a wild lifestyle and was unable to hold down a job. Her last job was as a nurse at a hospital, but she was fired after she stole prescription drugs—which she and her then-friend/partner-in-crime Tricia Staunton intended to sell on the black market.
