One of the best-known comediennes to emerge from the improvisational comedy scene of the 1990s, Amy Poehler performed tirelessly on Chicago and New York stages before making her mainstream breakout as a cast member of "Saturday Night Live" (NBC, 1975- ). She had previously starred in "The Upright Citizens Brigade" (Comedy Central, 1998-2000), a sketch comedy show created by the improv group of the same name, which morphed into a hotbed of emerging talent. During her seven-year run on "SNL," Poehler skewered celebs like Kelly Ripa, Avril Lavigne and Sharon Osbourne; served as co-anchor of Weekend Update; and delivered a memorable impression of then-Senator and presidential candidate, Hillary Clinton. Poehler transitioned successfully to the big screen with a pair of Tina Fey-scripted features, "Mean Girls" (2004), and "Baby Mama" (2008). Maintaining a foothold in television, Poehler was the creator of the charming animated series "The Mighty B" (Nickelodeon, 2008- ) and the star of the small town-set sitcom "Parks and Recreation" (NBC, 2009-2015), while her additional in-demand status as a voiceover actor made her one of the most successful cross-media comics of her generation.
