An issue filled film

Rating: Null/10 (14 October 2007)

Sacha Baron Cohen, is he the British Robin Williams or what (this isn't a question.)
This seemingly low budget film was made in the manner of Candid Camera, except this had a visible camera crew keeping straight faces shooting an unsuspecting unpaid uncontracted non-union supporting cast of thousands. The question raises its ugly head, did they all sign releases? SAG minimum perhaps for those whose voices were clearly heard speaking meaningful words, but what if they refused the bait? Can't be. Ordinary-people ignorant, but isn't that risky? Are the producers and distributors open to a class action suit? We'll see. This, too, is America.
Oh yes, I thought that all these kept-in-the-dark people delivered first class completely believable performances aka natural behavior, no actory shtik to be seen anywhere. Ensemble performances professionals should envy and audit. Indeed, we have already learned that anyone can act in this age of digitally made movies, and the trick for those without training is to find out what's stopping them. Professionals be warned!
2 questions: Why does one have to be rich educated Jewish to get away with anti-semitic comedy bits? And how did this movie deal with all of these to me more interesting social and business issues, with the grosses going well into nine figures worldwide?
