1. Roseanne Barr (Then)
Roseanne Barr, who portrayed the sitcom's eponymous character, was originally scouted by the show's executive producers, who were drawn to her loud, "domestic goddess" persona. They envisioned a sitcom helmed by the domineering, but lovable matriarch of a blue-collar family. Roseanne Barr fit the bill perfectly and would go on to win an Emmy for her role as Roseanne Conner.
