This may surprise many of you, but Shirtley Henderson was born on December 24, 1965! In Chamber of Secrets she played a teenager when she was really in her late 30s. She had me fooled. Films that Henderson has appeared in include Bridget Jones: The Edge of Reason (2004), Bridget Jones's Diary (2001), and a slew of smaller projects such as Villa des roses (2002) and Doctor Sleep (2002).
