The beloved sitcom The Golden Girls ended because one of the leads, Bea Arthur, decided to leave the show. Arthur played Dorothy opposite Betty White’s Rose, Rue McClanahan’s Blanche, and Estelle Getty’s Sophia. Unlike other sitcoms with multiple leads, The Golden Girls was a true ensemble, as each character was pivotal in the show’s overall vibe. So, it was a shock when Arthur announced that she was walking away from the project, effectively setting up its end.
