Sports betting is my only form of gambling.
Top 3 gambling movies I have enjoyed :
Number 1 Rounders : If u havn't seen it and are into gambling chances are u will relate to and enjoy it. Very good movie based around poker.
Forgot that one, you're right, it's a top movie.
Number 2 Bolier Room : Based around stocks. Solid movie.
I wouldn't say this is a gambling movie as such, but I see what you mean. More like a fradudalent movie.
