The miniseries, 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.

In 2006, Helfer appeared in the motion pictures Spiral and The Green Chain.

Helfer has been married to lawyer Jonathan S. Marshall of Marshall Wight LLP since 2003. She is represented by Gordon Gilbertson of Gilbertson Kincaid in Santa Monica, California.

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 will also be playing 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.
