A federal appeals court has revived a copyright suit against the filmmakers behind the Academy Award-winning movie “The Shape of Water.”

In an unpublished decision issued Monday, a three-judge panel of the U.S. Court of Appeals for the Ninth Circuit reversed a lower court win for studio Fox Searchlight and MacMillan Publishers, which published a novelization of the film, in a case brought by the son of Pulitzer Prize-winning author Paul Zindel, who claims that the film and the book infringe copyrighted elements of his father’s play “Let Me Hear You Whisper.”
