Couldn't agree more. Rounders are definitly the best poker movie ever made, no discussion on that - perfect insight of a live poker player's life.. (too bad they filmed it before internet poker era began)
Second part is just a gossip, altough Matt Damon and Edward Norton publicly said years ago that they would like to film a second part... but nothing is officaily confirmed yet..
Like pretty much everyone has said here Rounders for sure. Though I wouldn't say it's very realistic at all. Sure does make you want to play some poker though! It's been my favorite move since it came out when I was young. Checkoslavakia lol.
