There's a great article by Charles McGrath at the New York Times on Ian Fleming the author of the James Bond books (his 100th birthday will be on Wednesday). I love how the article goes into detail on the difference between the print and film versions of the series:
That License to Kill Is Unexpired
"Albert R. Broccoli, a producer of the first 17 Bond films, could be said to be a co-creator of this other, meta-Bond. It was he or his writers who made a trademark of the “Bond. James Bond” line, for example, and who insisted on the “shaken, not stirred” business. Fleming’s Bond is not nearly so fussy about what he drinks, as long as there is plenty of it. He’s as apt to slug down bourbon as a martini. This Bond is also much more fetishistic about smoking than he is about drinking and makes a point of ordering his cigarettes (with three gold bands on the filter) from Morlands of Grosvenor Street. (In a pinch, though, he’ll also smoke Chesterfield kings by the carton, and it’s little short of miraculous that he can climb a flight of stairs, let alone swim for miles, as he so often does.) He likes fast automobiles but hates gizmos, except for the odd concealed knife, and wouldn’t get caught dead with the laser watches, ejector seats, tricked-out cars and exploding key chains the movie Bond has been kitted out with, not to mention that embarrassing jet pack."
