Marge Simpson voice is performed by Julie Kavner, who also does the voices of Marge's mother Jacqueline and her sisters Patty and Selma. Kavner had been part of the regular cast of "The Tracey Ullman Show". Voices were needed for the shorts, so the producers decided to ask Kavner and fellow cast member Dan Castellaneta to voice Marge and Homer rather than hire more actors. Part of Kavner's contract says that she will never have to promote "The Simpsons" on video and she rarely performs Marge's voice in public because she believes it "destroys the illusion. People feel these are real people."
