Zelda May Rubinstein (May 28, 1933 – January 27, 2010) was an American actress and human rights activist, known as eccentric medium Tangina Barrons in the Poltergeist film series. Playing "Ginny", she was a regular on David E. Kelley's Emmy Award-winning television series Picket Fences for two seasons. She also made guest appearances in the TV show Poltergeist: The Legacy (1996), as seer Christina, and was the voice of Skittles candies in their long-running "Taste the Rainbow" ad campaign. Rubinstein was also known for her outspoken activism for little people and her early participation in the fight against HIV/AIDS.
Rubinstein died in Los Angeles, California, on January 27, 2010. She was 76. Eric Stevens, Rubinstein's agent for the past four years, said the actress had never recovered from a mild heart attack she suffered several months earlier, which he said left her a patient at Barlow Respiratory Hospital in Los Angeles. "She had several pre-existing conditions that she had been dealing with for years, and unfortunately they began to overtake her," Stevens said. Stevens also said that per Rubinstein's request, no funeral would be held.
