To Walk Invisible will star Jonathan Pryce as the novelists' father, and reunite Happy Valley actors Charlie Murphy and Adam Nagaitis as sister and brother Anne and Branwell Bronte.
"I am such an admirer of Sally Wainwright that if she were filming the phone book I would want to be in it!" said Pryce. "Her film will be a characteristically honest look at the whole Bronte family."
The immensely popular show returned to our screens in early February, welcoming back tormented police woman Catherine Cawood (Sarah Lancashire) and TV’s most feared man, James Norton as rapist Tommy Lee Royce.
Crime drama Happy Valley will be returning to screens later this year after being commissioned for a second series.
The Yorkshire-based six-part drama starring Sarah Lancashire focuses on a police sergeant searching for a kidnapped girl.
Happy Valley attracted an average of 7.2 million viewers during its first season, with its final episode in series one attracting 7.8 million.
Lancashire won the Female Actor award at the RTS Programme Awards in March this year.
The economic arguments for diversity came under the microscope at a lively joint RTS/BBC session held at New Broadcasting House last month. The panellists agreed that, following years of inaction, broadcasters are finally making an effort to boost black, Asian and minority ethnic (BAME) representation in television.
