Anecdotes

During the filming of Poltergeist III (1988), she was doing a photo shoot when she paused and lurched. Director Gary Sherman was present and asked her what was wrong, she responded with a comment like "I don't know, was just a jolt. I'm fine." Several minutes later Sherman was pulled aside and told they would have to let Rubenstein go from the film - her mother had just died. After developing the film from the photo shoot, it was discovered that every photo had come out fine, except one, which had an inexplicable cloud of light clouding into the photo from Rubenstein's left, covering half of her with a semi-transparent haze. Rubenstein said she knew the jolt had to have been her mother's passing - she said they always had a particularly strong bond, in a way some identical twins have. Sherman, who had witnessed it, agrees it could not have been anything else. Both Rubenstein and Sherman were already very well aware of the tragic events which had plagued the film series.

She formed the non-profit Michael Dunn Memorial Repertory Theatre Company in Los Angeles in the early 1980s. It was named after the late Oscar-nominated actor, also a little person and highly successful on film and TV. The membership included actors whose height ranged from 3'8" to 4'6".

She was seriously considered for the role of Shadout Mapes in Dune (1984).

Was one of the first celebrity AIDS advocates.

She attended the first AIDS Project Los Angeles AIDS Walk in 1985.

Attended the University of California and the University of Pittsburgh.

Filmed a scene in Casper (1995) wherein she portrayed her character from Poltergeist (1982) being shot from a chimney while yelling "Don't go into the light!" It didn't make the final cut, however.

The role of Mr. Pickett in Paganini Horror (1988) was originally a woman and was written with Rubinstein in mind.

Her agent was Eric Stevens.
