The "original" James Bond (David Niven) is a stalwart, upright English gentleman of the aristocracy (even if he has an illegitimate daughter by his lost love), while most of the other characters are slippery, treacherous spies. Of course, everybody's a comical one-note stereotype (especially the Scots!) rather than real people. Gambling is portrayed as a heroic endeavor.
Slapstick brawling, falling, punching, and martial arts (including one sequence in which seductive women are rebuffed by judo-flips). Much gunfire, but rarely any blood. One character is visibly shot in the head, and another is in a phone booth that explodes. Birds are hunted with rifles. Explosions, bows and arrows, and military artillary.
Much non-clinical sexual innuendo and beautiful, scantily-clad girls. One actress is entirely nude and covered just by strategic metal restraints on a table. A few others are fleetingly glimpsed covered in gold body paint. A man and a teenage girl take a bubble bath together. Mostly the sex is all talk ("Doodle me!" a Scottish vixen says), with hallucinatory montages of female faces in ecstasy as the only action. A young woman reassures her own father than she's not a virgin.
Some use of "damn." Jean-Paul Belmondo repeatedly utters a French swear word (inaccurately translated as "ouch").
Fancy motorcars on display, with the Lotus Formula Three getting a real salute. The James Bond franchise, at the time this movie was made, was already a commercial industry, with novels, toys, clothes ... even 007 deodorant. You can imagine what it's been like since.
Drinking, Drugs & Smoking
Social drinking, with a whole household rendered unconscious from (drugged?) whiskey. One character has a "trip" after his cocktail is drugged. Another character is called a junkie. The villainous LeChiffre puffs a cigar.
