Known as "Disney's Folly" when it was in production, "Snow White and the  Seven Dwarfs" (1937) was so successful that it made possible the  animated features of Disney's golden age ("Pinocchio," "Fantasia") and  provided the inspiration for countless parodies and updates  ("Enchanted"). The template: beautiful princess flees jealous queen,  finds sanctuary with crusty but harmless bachelor miners, bites apple  and dust.
While Snow White was hand drawn, the model for her was very much alive.  Dancer Marge Champion was used by Disney animators to make sure that  Snow White's movements were realistic. This was not her only claim to  fame, however. She teamed up with husband Gower Champion   to appear in a number of MGM's fabled musicals ( "Show Boat," "Lovely  to Look At") before becoming a choreographer in her own right.
The "Snow White and the Seven Dwarfs" DVD was released Oct. 6, 2009.
A: Yes. I turned 90 this month. I  still have my marbles, and I'm still dancing, and I still remember a lot  of the things that happened to me when I was 14. Because I went to work  for Walt Disney   when I was 14.
Q: How did you come to his attention?
A: They needed a young girl   who they could really get the personality out of because the animators  put their own personalities in the animals and dwarfs. They had a talent  scout looking in dancing schools for girls who could move and do  improvisation. This scout picked three of us out of my father's dancing  school. I didn't hear from them, and I had forgotten all about it until  they said, "Come over to the studio and get measured for a costume."  Incidentally, last week they showed me the bodice to the dress I wore.  And we could tell that somebody else had worn it and been dismissed or  something, because there were two sets of hooks and eyes. I was so  astonished when they showed it to me because that was something that  nobody ever told me.
Q: Did they film you?
A: Yes, they filmed me in 16mm on  one of the sound stages with very crude scenery. When I was running  through the forest they hung a clothes line with a lot of ropes from it  so I could improvise going through the forest and the weeds catching my  dress and my reaction to that.
Q: I'm thinking especially of that dancing sequence with the dwarfs.
A: When it came to dancing with the  two dwarfs one on top of the other with a long coat on, I danced with  Ollie Johnston   because he was the tallest animator, so that my eye line would be  correct.
Q: What about sight lines with the dwarfs?
A: There was a time when I was  shooing them off to work and the animators who were assigned to that  section were backing up on their hands and knees because my eye line had  to be down there.
Q: I didn't realize it was that detailed. I just assumed they were using you as a rough sketch.
A: If you want to know how detailed  it was, I had to learn to lip sync when I was doing "Someday My Prince  Will Come." When I first saw the storyboards, Snow White looked like  Betty Boop. She had round eyes and little eyelashes and a tiny little  waist and all of that. After they started using me as a model, they  loosened her waistline and made her eyes almond-shaped.
Q: Did she look like you at all?
A: The hair was different, because  she had black hair. The first day I worked they had gotten a football helmet   and painted black hair   on it and put it on my head. By lunchtime I was nearly fainting because  it was so hot under there. And they had a big conference and decided  that they could figure it out (without the helmet).
Q: How much time did you spend being filmed?
A: I was on that for about two  years, but I only worked one or two or three days a month because I  could do enough to keep them busy for weeks.
