TVLine has learned exclusively that the Smallville alumna, Erica Durance, is set to guest-star on NBC's Harry's Law, as a psychologically infirm woman who retreats into the persona of the DC Comics heroine to help wreak revenge on perpetrators of domestic abuse.

Erica Durance will appear in the legal dramedy's 11th episode, which given NBC's midseason schedule change-up does not at this moment have a firm air date.

The storytelling twist affords Harry's Law creator David E. Kelley the chance anew to tap into the Wonder Woman mythos, after his pilot starring Adrianne Palicki as the Amazonian princess didn't make the Peacock's 2011-12 schedule.

Harry's Law was just picked up for a full second season and is currently airing on NBC.
