As I read Sam Wasson's breezy, cocaine-dusted history, roughly two-thirds of which is about director Roman Polanski's Chinatown, I kept wondering: How would it be different if Faye Dunaway had agreed to talk? Dunaway, an easy target in recent years, continues to be in Big Goodbye, which emphasizes her tardiness and unpredictability. But, reading between the lines, it's hard not to wonder what it was like to be virtually the only woman on set, one whose director disliked her and whose key scene is of her being smacked in the face repeatedly by her co-star, Jack Nicholson. Wasson didn't speak with him, either.
