Gus' and Hazel Dobkins' AGE
He said he couldn't get her killing spree out of his head for years, but given that the movie is set in the present (1991/1992) he would only have been about 11 when it happened in 1956 and 20 when she was released from prison in 1965. So how would he have known about it? The movie seems to be implying Gus was on the case, but he's too young. George Dzundza was born in 1945 and was maybe around 46/47 during filming. He didn't even look that old. What do others think?
Another incongruity is when Nick tells Gus that Johnny Boz was a rock star "before your time." The actor who played Boz is a year younger than Dzundza. Why did Nick say that? Time has nothing to do with it. Maybe Gus just wasn't into rock music. Boz wasn't that big a star anyway if he only had $5 million. Maybe just bad script writing because Joe Eszterhas was sloppy from using as much cocaine as Johnny Boz?
