There was that extremely campy serial that was part of NBC's Cliffhangers where the very plucky Ms. Anton found herself in one precarious situation after another. She was supported and hindered by Michael Swan, Marj Dusay and Ray Walston. It was titled Stop Susan Williams! Which NBC did rather abruptly, as the final cliffhanger was left unresolved.
More recently, Susan played the Velma Van Tussle part in a production of Hairspray that sounded like a blast.
