I never saw any of the Poltergeist films, so I didn’t know Zelda Rubinstein from that series of films — rather, I knew her from a David E. Kelley show that aired in the mid-1990s, Picket Fences. She played sharp-witted Ginny Weedon, a dispatcher with the Rome, Wisconsin Sheriff’s Office.
Unfortunately, there aren’t many good clips of her from the show. Alas. Rest in peace, Zelda.
(And put the rest of that show out on DVD, Fox!)
