Mary Lynn Rajskub

After receiving her start in performing arts and comedy theater, actress Mary Lynn Rajskub made a name for herself as one of the original members of the sketch comedy series, "Mr. Show" (HBO, 1995-99). Rajskub left the show following its debut season in order to replace friend Janeane Garofalo's character on "The Larry Sanders Show" (HBO, 1992-98), playing the show-within-a-show's eager-to-please and often inappropriate guest booker. Having proven herself a dynamic comedic player on the small screen, she made the transition to features with small roles in "Road Trip" (2000) and "Storytelling" (2001) before landing a more significant supporting role opposite Adam Sandler and Emma Watson in "Punch-Drunk Love" (2002). Though most of her career to that point had a comedic bent, Rajskub made the surprising jump to drama with a high-profile supporting turn as the unconventional CTU analyst Chl O'Brian - one of the few people trusted by Jack Bauer (Kiefer Sutherland) - on the hit action series, "24" (Fox, 2001-2010). Though she spent most of her time behind a computer terminal aiding Bauer in whatever manner she could, Rajskub earned a loyal following, including within the real-life Homeland Security department which named a research and development program, "Project CHL ," in homage to her character. Both during and after the successful run of "24," Rajskub was featured in several films including "Little Miss Sunshine" (2006), "Sunshine Cleaning" (2008) and "Julie & Julia" (2009), all of which demonstrated the range and versatility of the talented young actress.
