Sacha Baron Cohen's least favorite Ali G interview: David Duke

In this reddit AMA, Sacha Baron Cohen talks about his least favorite Ali G interview subject:

My least favorite was I did an interview with David Duke as Ali G, and it was quite unpleasant because he brought some neo-nazi security with him and my researcher had to spend the evening keeping the security guards away from me. And even though my researcher is Jewish, he had to pretend to be a complete antisemite and neo-nazi in order to keep the body guards attention and let me interview Duke alone. In the end, I never showed the Duke interview, because his views are so extreme and horrifying that giving any publicity to him felt immoral.
