Tricia Helfer is a Canadian supermodel and actress best known for her role as Number Six in the television sci-fi series Battlestar Galactica, and the 2003 mini-series of the same name.
Helfer was born in the rural community of Donalda in Stettler County, Alberta. She was raised on her family's grain farm and at the age of 17, while standing in line at a local movie theatre, she was discovered by modelling agency scout Kelly Streit.
In 1992, she won Ford Models' Supermodel of the World Contest and was subsequently signed to the Elite Model Management and is currently signed with Trump Model Management.
She has appeared in numerous ad campaigns, including Ralph Lauren, Chanel, and Giorgio Armani. Helfer has walked for top fashion shows such as Carolina Herrera, Christian Dior, Claude Montana, Givenchy, John Galliano, and Dolce & Gabbana.
She has graced the covers of Flare, Amica, ELLE, Cosmopolitan, Marie Claire, and Vogue, among others. She also posed nude for the February 2007 issue of Playboy.
While working in New York as a model, Helfer hosted a Canadian television fashion program called Ooh La La. She relocated to Los Angeles in 2002 to pursue a full-time film career.
Her first acting assignment was a guest role as Sarah in two episodes of the television series Jeremiah. Thereafter she played the role of a model, Ashleigh James, in the May 16, 2002 episode "The Hunger Artist" on CSI: Crime Scene Investigation.
In 2002, Helfer played the female lead, Eva, in the independent film White Rush.
In 2003 she was chosen to play Number Six, the Cylon agent in the mini-series Battlestar Galactica. The mini-series, which was a remake of the 1970s series Battlestar Galactica, was a huge ratings success, due in part to the visually attractive mind games between Number Six and scientist Dr. Gaius Baltar.
It has now become a television series in which Helfer is a main cast member.
In late 2003 Helfer was offered the role depicting Farrah Fawcett in the NBC made-for-TV Behind the Camera: The Unauthorized Story of 'Charlie's Angels'.
She also regularly appeared in photo shoots by Maxim magazine and was the magazine's wall calendar girl for 2005. She was ranked #83 on the Maxim Hot 100 Women of 2005.
Concurrent with her role in Battlestar Galactica, Helfer began producing and hosting Canada's Next Top Model on May 31, 2006.
In 2006, Helfer appeared in the motion pictures Spiral and The Green Chain. She also appeared in Maxim Magazine in 2006.
Helfer has been married to lawyer Jonathan S. Marshall of Marshall Wight LLP since 2003.
In October 2006, it was announced that Helfer would not return to host the second season of Canada's Next Top Model in order to concentrate on her work on Battlestar Galactica.
Helfer also played a role in Electronic Arts Command & Conquer 3: Tiberium Wars, as a character named Kilian Qatar, along with her Battlestar Galactica co-star, Grace Park. She also guest starred in an episode of Supernatural in 2007.
In 2014 she had a starring role as Molly Parker - a badass member of the Texas Rangers whose fierce intelligence and strong feminine intuition, along with her Ranger training, enables her to get into the minds of the most dangerous female killers - in the short-lived police procedural crime drama television series Killer Women.
