Born on the outskirts of Toronto, classically trained Canadian actress Christina Cox attended the exclusive Arts York at Unionville High School, where she double majored in theater and dance. Graduating from that program, Cox applied and gained acceptance to Toronto’s Ryerson Theatre School, then later attained recognition and exposure as a screen actress in her native Canada — first in various guest appearances (as different characters) on the Alliance Atlantis television series Due South, then with a supporting role in the Steve di Marco-directed Canadian crime comedy Spike of Love.
Cox first moved to Los Angeles in the mid- to late ’90s. A number of her early appearances constituted guest spots on such programs as Andromeda, The Chris Isaak Show, and She Spies. She broke through to national fame in several capacities, however — namely, as one of the leads, Kim, in the lesbian romantic comedy Better Than Chocolate (1999) and with her ongoing portrayal of Angie Ramirez on F/X: The Series. Cox landed her most significant role up through that time as the heroine of the Vin Diesel fantasy adventure saga The Chronicles of Riddick (2004). In that film, the actress played Eve Logan, a mercenary soldier hired to deliver Richard Riddick (Diesel) to the planet known as Crematoria.
In 2006, Cox landed one of her first major leads, as Vicki Nelson — a private eye in for the ride of her life when she mistakenly confronts a 450-year-old vampire (Kyle Schmid) — in the fantasy television series Blood Ties, adapted from the Blood Books series of novels by Tanya Huff. In addition to her film work, Cox remains extremely active in theatrical productions.
