Erica Durance

Erica Durance, who starred on The CW's Smallville as Lois Lane, is about to kick some butt on Harry's Law (Wednesdays, 9/8c, NBC).

Durance takes on the role of a somewhat mentally unstable woman who believes she's Wonder Woman. Her character, Annie Bilson, will find herself on the wrong side of the law when she metes out her own form of justice. (Get the scoop on her role and what it was like to put on the superhero costume here.)
