Zelda Rubinstein, possibly best known for her role in the Poltergeist series, passed away Wednesday at the age of 76.

The actor was hospitalized two months ago after suffering a mild heart attack and rumours had been spreading across the net that she was close to death but her agent, Eric Stevens, has now confirmed she passed away of natural causes at Barlow Respiratory Hospital in Los Angeles.

She will be greatly missed. Her likeness and voice made her one of a kind.
