US actor Patricia Arquette has spoken to the BBC in an interview about gender pay equality in Hollywood, for Hollywood A-listers and also technical staff such as sound editors. Arquette's interview follows on from Jennifer Lawrence's recent essay "Why do I make less than my male co-stars", in which she discusses her feelings after finding out that she was paid less than her American Hustle male co-stars, one of whom, Bradley Cooper, has said in recent days that there needs to be much more transparency over pay in the film industry to lead to further equality.
