Film and television actress Estelle Harris made a career out of treating her onscreen family members with loving contempt. As Estelle Costanza on the now iconic sitcom, "Seinfeld" (NBC, 1989-1998), Harris was the tart-tongued mother of George Costanza (Jason Alexander) who hurled shrieks and insults at her aimless New Yorker son who never seemed to do anything right. She had a very distinct high-pitched voice that lent itself perfectly to portraying shrill relatives in films like "Playing Mona Lisa" (2000) and "Out to Sea" (1997), as well as bringing to life animated characters like the sassy Mrs. Potato Head in "Toy Story 2" (1999) and "Toy Story 3" (2010). While Harris had a late start in her career and played mostly nagging motherly figures, she still possessed an uncanny ability to give her characters depth and charm, and successfully endeared herself to audiences of all ages.
