As a side note, I found it interesting that Matt Damon and Edward Norton both played in the 1998 World Series of Poker at Binion's Horseshoe in downtown Las Vegas. The fact that they were eliminated relatively early made it a little difficult for me to accept them as poker pros on the big screen, but at least they were totally cool about it. Despite all of its attempts at realism, there is a fair amount of glamorization surrounding the game on the big screen. But what bothered me more was the way cards were dealt and chips were handled. It's all subtle and forgivable though, and most people probably won't even notice.
More significant problems come in with the writing.
Very often, the hardcore pros have to be made to look stupid in order for Damon's character to look like a genius. Mol does an admirable job, but basically can't salvage an uninspired role. In fact, all of the female characters in Rounders are little more than props. It might not be so noticeable were it not for the fact that Damon and Norton's characters are so well developed and defined. The contrast in characterization, therefore, is pretty glaring.
