BURBANK,CALIF. -- The sing er who provided the voice of Cinderella in the animated film has filed a $20 million lawsuit claiming that Disney violated her contract by producing videocassettes of the classic.

Ilene Woods Shaughnessy, who in 1948 was paid $2,500, said in the suit that her contract forbids Disney from making copies of the movie for sale to the public.

"In 1988, defendant Disney commenced production and marketing for sale to the public videocassette versions of 'Cinderella,' all of which has been done without plaintiff's consent," the suit said.

Steve Feldstein, a spokesman for the home video division of Disney, said the company had not seen the suit and had no comment.

Shaughnessy, who lives in Woodland Hills, was 22 when she provided the voice of Cinderella, said Dave Smith, archivist for Walt Disney Productions.

Walt Disney liked her clear delivery when he heard her sing for the movie's composers, according to company records kept by Smith.

She performed such songs as "So This Is Love" and "A Dream Is a Wish Your Heart Makes" for the movie, he said.

Shaughnessy also sang on radio programs, including "The Bing Crosby Show" and "The Paul Whiteman Show," Smith said.

The suit is similar to at least two others brought against Disney.

Singer Peggy Lee won a summary judgment in April against Disney in a suit in which she claimed the company needed her approval before releasing the videocassette version of "Lady and the Tramp."

Lee provided voices and co-wrote songs for the 1955 animated film.

Singer Mary Costa, the voice of the princess in the 1959 movie "Sleeping Beauty," filed a suit in May 1989 seeking royalties related to videocassette sales.

Shaughnessy asks for $10 million in damages for breach of contract and at least $10 million more for her contribution to the success of the videocassette.

Feldstein said he didn't know how many videocassettes of the movie have been sold.
