To Walk Invisible takes a closer look at the extraordinary lives of the Brontë sisters, who overcame many obstacles, to rise from obscurity to producing some of the greatest novels in the English language.
Speaking at a recent RTS event, Sally Wainwright explained her interest in the characters. She told audiences how when she wrote the script, she wanted the characters to reflect real life. She complained that past retellings of the story have seen actors with sparkling teeth and RP accents, describing it as “offensive.”
The recent controversy over poor-quality sound on the hit BBC One show Happy Valley has once again focused senior TV executives’ minds on the problem of inaudible dialogue in drama.
Last month, BBC Controller of TV Channels Charlotte Moore pledged to tackle the “big issue” of sound. She added that it was “incredibly hard to get to the bottom of where things go wrong”. She explained she had introduced a new set of best-practice guidelines to help avoid future problems with inadequate audio.
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."
