Occupation: Actress
Biggest accomplishment this year: Receiving a Critics Choice Television Award nomination for Best Drama Supporting Actress, for her role on Sundance Channel's Rectify

Mad Men fans remember Abigail Spencer as Sally's teacher in season three, the one Don has an affair with. Since then, Spencer has appeared in both TV and film in supporting roles. She has been nominated for the Critics' Choice Television Award for Best Drama Supporting Actress for her work in the Sundance original series Rectify, and appeared in Oz the Great and Powerful earlier this year. If you'd like to see Spencer in a leading role, you can find her as the star of The Haunting in Connecticut 2: Ghosts of Georgia. Yes, apparently there was demand for a sequel.
