Wayne Wang

Filmmaker Wayne Wang. With the films "Chan is Missing," "Dim Sum," "Slamdance" and "Eat a Bowl of Tea," to his credit, Wang was the first Chinese-American film director to make an impact in the American film industry. Wang went on to direct "The Joy Luck Club," and the films "Smoke" and "Blue in the Face." His newest film is set in Hong Kong, "Chinese Box" starring Jeremy Irons.

Some directors and distributors say the rating, often associated with hardcore pornography, amounts to de factor censorship of their movies -- many theaters won't play them, and advertising is hard to secure. MPAA President Jack Valenti, who invented the rating, director Wayne Wang, and Senior Vice President of Marketing Russell Schwartz respond to the controversy.
