Sacha Baron Cohen writes characters.
 HBO spokesman Quentin Schaffer has replied to criticism concerning Baron Cohen's characters, "Through his alter-egos, he delivers an obvious satire that exposes people's ignorance and prejudice in much the same way All in the Family did years ago"
 He adopts a variety of accents and guises for his characters and interacts with unsuspecting subjects who do not realise they have been set up
