Roley v. New World Pictures, Ltd.
The plaintiff Sutton Roley had a successful career as a director for television shows.

The defendant Walter Coblenz also had success as a movie producer, working on such films as All the President's Men.
Sister, Sister is a horror/drama about a pair of sisters who have to deal with the brother of a man they murdered years before. It did very poorly at the box office, taking in less than a million dollars overall. Its credited writer, Ginny Cerrella, only wrote one other movie screenplay, the box-office flop Hot Chocolate.
