Casino Royale

I haven't watched a James Bond movie in years. The last one I saw was You Only Live Twice and I was maybe ten or eleven at the time, so it's been over a decade. Much like how I feel about Star Wars, I'm glad James Bond movies are a thing and I'm a fan of their existence but not really of the movies themselves. I don't want to watch them but I'm glad they're there.
That being said, the Casino Royale I just watched is likely not the version you're thinking of. Of course I'm not a mind reader and I don't know who you are so it could very well be exactly the one you're thinking of. It's certainly not the new Casino Royale, though, and it's not the comedy starring David Niven.
This was, as far as I know, the first onscreen version of James Bond. It was an episode of the television show Climax! and good ol' Jimmy Bond was played by American actor Barry Nelson (who I'm going to start telling people is my favorite James Bond, just to be contrary).
The reason I watched the movie (the reason I heard of the movie and, according to IMDB, the reason Barry Nelson took the role) is Peter Lorre, who plays the villain. I love Peter Lorre.
The movie's pretty straightforward: a Soviet spy gambled away all of his country's money and now he has to win it back. Jimmy Bond has to play against him and make sure he doesn't get that money. Thrown into the mix is Bond's ex-girlfriend who works for the Soviets (or does she?) and ... actually, that's about it.
There's almost no action (a few poorly-thrown stage punches, a couple offscreen gunshots and it's implied that Peter Lorre pulls out a couple of Bond's toenails with pliers) and a lot of talking. And a rather long scene of Bond and the villain playing baccarat.
It was entertaining enough, a good way to spend about an hour, but it was nothing like what society's general consensus of how James Bond goes. I'm cool with that, though. In fact, it makes me very happy that the first James Bond movie was a poorly-received television episode with a schlumpy American of a Bond (well, maybe not schlumpy but he's definitely not suave nor badass) and almost no action.

End of line.
