Hooks joined SNL in 1986 as a part of a cast that included Dana Carvey, Phil Hartman, Jon Lovitz and Dennis Miller. She made a name for herself on the sketch show through her spot-on impersonations of Bette Davis, Betty Ford, Nancy Reagan, Sinead O'Connor, Jodie Foster and Hillary Clinton.
The Georgia native was nominated for an Emmy in 1998 for her guest role on 3rd Rock From the Sun and was most recently seen on television in NBC's 30 Rock as Verna Maroney, the mother of Jenna Maroney (played by Jane Krakowski).
After her appearance on 30 Rock, Tina Fey said in 2013 that it was one of her all-time favorite episodes of the show. "I love Jan Hooks so much," she said, "and for her to come in as Jenna's mother was really great."
Other film and TV credits include Designing Women, The Simpsons, Futurama, The Dana Carvey Show, Primetime Glick, Batman Returns and Simon Birch.
