Cynthia Preston fell into acting quite by chance. It was while she was attending high school in Toronto, that her mother suggested a self-improvement course in order to help her overcome extreme shyness. As a result, Cynthia took up modeling at fifteen, and soon found herself working overseas in Japan for months at a time.
Not long after graduating from high school, she was summoned by CBS talent scouts, and landed the role as Jill Clayburgh's daughter in the made for television movie, Miles to Go. After that, she continued to find work in some rather offbeat, campy movies like Pin, The Brain and Prom Night III, as well as doing quite a bit of voice work on a variety of animated projects; perhaps the most popular that of Princess Zelda on the Mario Bros. cartoon series.
Over the years she has kept busy with interesting choices, like playing the mentally disturbed groupie in Whale Music, the lost soul in the creepy supernatural thriller Convergence, and spent a year as the complex wife in the Showtime TV series Total Recall 2070. Cynthia has done quite a bit of episodic television including the series CSI, Bones, Two and a half Men, Numbers, and Andromeda among many others. Fans of "The X-Files" may remember her from the episode "Folie a Deux", where she played a telephone solicitor who gets transformed into a white-eyed, skin-peeling zombie.
Cynthia also appeared in Thom Fitzgerald's film "The Event" which premiered at the 2003 Sundance Film Festival.
From 2002 to 2005 Cynthia played the character Faith Rosco on the popular soap "General Hospital."
The feature film Whale Music, in which Cynthia was the lead actress, opened the Toronto Film Festival in 1994 and was also nominated for Best Picture in Canada.
