In the third lecture of the 2013 series, American screenwriter Susannah Grant (Erin Brockovich, Pocahontas, The Soloist) talks about the importance of the screenplay's integrity and 'unique voice', the necessary hard work (rather than genius) screenwriting entails and why the endeavour 'guarantees humiliation and abuse'. Recorded at the BFI Southbank on 28 September 2013.
