An online resume for actress Sarah Jayne Dunn lists the her most recent credit as appearing in 'The Dark Knight'. What's surprising though, is Dunn is credited as playing "Harley Quinn" in Christopher Nolan's Batman sequel.
Fans know that Quinn is, the Joker's girlfriend, a character created for the Paul Dini/Bruce Timm animated 'Batman', series. In short order she became one of the most sensational Batman rogues, taking a place among his top tier of villains. Eventually the character transitioned into Batman canon, appearing in the comics as well as other spin offs, like the ill-fated 'Birds of Prey' TV series.
Fans will have to wait and see if Quinn appears in full harlequin gear and makeup in the movie, or is a bit player in Joker's army, waiting to explode into the next sequel.
Dunn is largely known for her work on British television.
