Ellen writes of this movie in her 2006 autobiography
If you like this movie, you should check out Ellen Burstein's autobiography "Lessons in Becoming Myself." There's 15-20 pages of material and a page of photos and a lot of trivia that can be added to this IMDb entry (a real-life healer was a technical advisor on the film and healed someone who had an accident on the set, the fly on her toe was that last one of 10 they tried, her mother was an extra in the movie, Ellen believes in psychic powers herself, etc.).
The following is from Wikipedia's entry on psychokinesis where the film is mentioned:

In her 2006 autobiography, Burstein writes at length about the making of the movie and reaction to it, "I still have people approach me on the street and tell me how important the film was in their lives... Some people have told me that they stopped denying their psychic abilities after seeing the film and actually developed them instead of hiding them for fear they'd be thought weird. Some people, many in fact, told me they went into the healing profession because of the film. And others told me about feeling healed by the film."
