Ultimately the movie's message is that money can't buy you happiness or love, and you can't get true love without growing up and cleaning up your act. That said, Arthur does start out by agreeing to marry a woman he doesn't love (or even like) just so he can keep his inheritance and wildly spend it on frivolous things. And, of course, there's his frequent drinking -- which, while not exactly glamorized, doesn't have particularly harsh consequences, either.
Arthur is manhandled by a woman. He's also threatened with a table saw.
Lots of innuendo-laden talk. Early in the movie, Arthur is caught in bed with a barely dressed woman. Couples kiss, and one woman shows up at a man's doorstep clad only in lingerie and an overcoat. A woman is shown astride a man (no body parts are shown). A man parades around the city in his knickers; he also strips down to them in a church. Jokes about body parts.
Mostly "bloody," "hell," "bugger," and "prick," though there are also a couple of uses of "s--t," plus "t-tties," "oh my God," and "goddamn."
Brands include Maker's Mark (prominently), Sony, Jelly Belly, and Dylan's Candy Bar.
Drinking, Drugs & Smoking
The main character is always soused (champagne, hard liquor, etc.); though he tries to attend an AA meeting at one point, he makes fun of it. He's also shown smoking a hookah.
