Before Saturday Night Live, Shannon had a struggling career in films, her most notable being a supporting role as Meg in the 1989 horror film remake of The Phantom of the Opera with Robert Englund. In 1991, she had a brief appearance in the second season of Twin Peaks, and in 1993, she appeared in a supporting role in two episodes of In Living Color, the first in a fake TV commercials with Chris Rock (played by Shawn Wayans), and the second in a sketch with Jim Carrey, playing a crooked police chief.
Shannon's major break came in February 1995, when she was hired as a featured player on Saturday Night Live to replace Janeane Garofalo after Garofalo left mid-season. Shannon was one of the few cast members to be kept (along with David Spade, Norm Macdonald, Mark McKinney, and Tim Meadows) when Lorne Michaels engaged in a major cast overhaul between seasons 20 and 21.
She appeared in a 1997 episode of Seinfeld entitled "The Summer of George," where she played Sam, the co-worker who drove Elaine Benes crazy because she did not swing her arms while walking. She also appeared in Sheryl Crow's video for the song "A Change (Will Do You Good)" and played the recurring role of loony neighbor Val Bassett, Grace Adler's nemesis, on Will & Grace, appearing in five episodes over the sitcom's eight-season run. In 1998, she played the role of Emily Sanderson in the film A Night at the Roxbury, featuring Will Ferrell and Chris Kattan who were also cast members of SNL at the time.
In 1999, Shannon starred alongside Will Ferrell, in Superstar, a feature film based on her most famous SNL character, Mary Katherine Gallagher, the awkward Catholic school student who aspires to be a musical superstar.
Shannon left SNL in 2001, surpassing Victoria Jackson as the show's longest-serving female cast member (she has since been surpassed by Rachel Dratch, Maya Rudolph, and Amy Poehler). Later, she acted in the 2003 romantic comedy My Boss's Daughter.
In 2004, she starred in a short-lived Fox network television series Cracking Up with actor Jason Schwartzman. That same year, she guest starred in an episode of Scrubs and starred as Mrs. Baker in the film Good Boy! . In 2006, Shannon was featured in the Sofia Coppola directed movie Marie Antoinette as Aunt Victoire. The next year, Shannon guest starred on ABC's Pushing Daisies and the film Evan Almighty. Shannon also made a rare move to drama, appearing in the critically acclaimed film Year of the Dog in 2007.
Shannon hosted Saturday Night Live on May 12, 2007, making her the second former female cast member to host (after Julia Louis-Dreyfus).
Since September, 2008, Shannon has starred as Kath in the US version of the hit Australian sitcom Kath & Kim.
In 2008, she also starred in an episode of the comedy series Pushing Daisies and the TV movie More of Me.
