Bel Ami is filled with negative messages about class, fortune, marriage, and sexual relationships. The over-arching theme is that people born into money take it for granted, and those who have to work for their pennies (or francs as the case may be) will stop at nothing to keep their riches.
Georges gets into a fight at a brothel/gambling hall, and one man dies from consumption in a bloody manner.
From the opening sequence, when Georges flirts with and eventually solicits a prostitute, Bel Ami is highly sexual. Nudity includes breasts, backs, butts, and basically everything except full-frontal genitalia shots. There are more than a half-dozen sex scenes, which range from semi-clothed romps to explicit depictions of lovemaking. Georges is a 19th-century gigolo and is depicted as irresistible to the wealthy women in Madeleine's social circle.
One "f--k," plus insults like "whore," "idiot," and other derogatory terms.
Drinking, Drugs & Smoking
Several characters smoke cigarettes (accurate for the era), and there's a lot of drinking at the brothel and at every social gathering.
