Sonia Jackson is an American actress, known for Jurassic Park III (2001), Speed (1994) and Death Becomes Her (1992). Having past the ingenue stage of life when she started her acting career, Sonia went directly to stand-up and then expanded into film, television, stage, commercials and more. Her characters have varied from the salt of the Earth as nannies, nurses and teachers to those of convicts and prostitutes. She is recognized on the street most often for her role in It's Always Sunny in Philadelphia as a crack whore. Sonia's continuing project is Conversations 'Bout the Girls, her play which examines a woman's relationship with her breasts and how it's changed by the world around her.
