It's a comedy, but the movie does include the violent aspects of a Western -- including violence against women and the plundering of a village. But there's heart behind the amigos' movie-star facade.
Lots of Western-style shootings in which dozens of people are killed. No blood or gore, but a real emphasis on gunplay -- though much of it is played for humor. Graphic threats about killing. References to rape and forcing a woman to have sex under the threat of death (also presented within the context of the film's comedic tone).
Some exchanges/one-liners about sex. (For example: "You know what foreplay is?" an old woman asks the innocent Carmen. "No," she replies. "Good. Neither does El Guapo.") Kissing scenes.
A few uses of words like "s--t," "d--k," "hell," "ass," "balls," and "damn."
Drinking, Drugs & Smoking
Upon arriving in Mexico, Dusty orders a beer but is given tequila instead. The guys then drink shots of tequila and make hilarious faces. Later in the movie, serious tequila drinking goes on among El Guapo's gang. Very drunken behavior follows.
