The 31-year-old gave birth to her daughter in 2005, her first child with longterm partner actor David Thewlis, and admits her relationship with the tot became the basis for the character of Charlotte "Chuck" Charles in the hit drama series.
She says, "I would never had got the part if it wasn't for Gracie. I play a woman who is brought back from the dead and can only live if her lover never touches her.
"The whole point about her is she has this second chance at life. I looked at Gracie and the way she thinks opening a box of cornflakes is a wondrous event and just thought, 'I'll play it like I'm seeing life through her eyes.'"
