Keira Knightley was "not aware" of the boycott of Audible's Harry Potter series before signing up to the project.
The 40-year-old actress - who voices Dolores Umbridge in the upcoming audiobook series - insisted she didn't realise some fans had pledged to avoid the project in protest against author J.K. Rowling, who has faced criticism for her alleged anti-trans views in advocating for the importance of single sex spaces.
