Ian Fleming wrote the novel in 1953, introducing James Bond to the world. (I still haven't, but I will get around to it!) I recently purchased it because the DVD also includes 'Casino Royale' from the TV series 'Climax!' and I have never seen that one. I don't think I have seen it in full since that time, when I was just 17 years old.
I saw Casino Royale (1967) when it first came out, once again at the Keswick Theatre in Glenside, PA.
