(L) Queen Mother Dr. Delois Blakely, (R) Whoopi Goldberg in "Sister Act"

*Nearly two decades after the Whoopi Goldberg film “Sister Act” hit theaters, Walt Disney Co. and Sony Pictures are being sued by a woman who claims her autobiography actually inspired the movie and subsequent stage musical.

The plaintiff is Delois Blakely, representing herself with allegations of breach of contract, misappropriation of likeness, unjust enrichment and other claims, according to The Hollywood Reporter.

The complaint states Blakely was a “young, Black, singing nun serving the street people and youths of Harlem,” who published the autobiography, The Harlem Street Nun in 1987.

That year, she reached out to others in the industry with a three-page synopsis, including Tri Star Pictures producer Cynthia Bowles. The film executive is said to have mailed a letter back expressing interest in movie rights.

Later, according to the claims, producer Scott Rudin took a Sister Act project from Tri-Star to Disney and went on to executive produce a film that made more than $230 million at the box office, as well as producing a sequel and a Broadway musical. The studios declined to comment.

Blakely, who was profiled in the New York Times in 2003 as Harlem’s Queen Mother, lays out the similarities, and is now demanding an injunction against further violation of her publicity rights and equitable relief.
