A good film, but doesn't contain much poker. Interestingly enough, I heard this was where the producers of Batman v Superman got the idea for Affleck to play Bruce Wayne.
Documentaries can highlight a series: "Lessons poker school pokerstars".
Recently saw a good video documentary "Bet Raise Fold (2013)
Movies about poker has little in common with the game generally have. Well, the most funny in my opinion "Maverick" (1994). Especially at the end with a Royal flush. And a movie with Celentano "Asso" (1981) funny
I've seen lots of films that have poker but the only two I know of that are based on poker are Rounders and Maverick.
Rounders was alright but nothing special in my opinion. However Maverick I first saw when I was younger and have loved it ever since.
