Well Casino Royale comes instantly to mind

Also the oceans series.

I fact I've noticed many heist movies have one. Not just oceans 11 etc where the heist in based at a casino. I could talk about why for an hour but I'll spare you.

I believe rififi starts this way

The Ocean's 11 (2001) comes to mind as does a couple of episodes of West Wing that had scenes with card games.

I seem to recall Maverick(1994) having a good card game as a central plot element, which takes place on a river boat casino. It's also just a really fun movie about three competing con artists (played by James Garner, Mel Gibson, and Jodie Foster).

It's been a few years since I've seen it, and it's set in the old west, so sorry if it has any racisms I forgot about!
