Actors Who Appeared On Law & Order Before They Were Stars

Kate Mara, Rooney’s Sister, Also Appeared On The Show

Rooney Mara isn’t the only member of her family who worked on Law & Order early on in her career. Her sister Kate appeared on the show in 1997 as Jenna Erlich, whose bail bondsman father is murdered. Mara went on to appear in several more TV shows, including Cold Case, Boston Public, CSI: Miami and CSI: Crime Scene Investigation. While she worked steadily in Hollywood, she didn’t really make her mark until she landed the role of Zoe Barnes in Netflix’s House of Cards and computer analyst Shari Rothenberg in FOX’s 24. She has also appeared in American Horror Story: Murder House.
