Though it doesn't start out that way, the movie is eventually about making ethical choices and showing empathy for others. In the beginning, Wyatt and his brothers are tired of being lawmen and wary of the danger involved. Now they just want to make money from gambling casinos. Trouble arises, and the brothers try to stay out of it as long as they can, but eventually they realize that they must do the right thing. It could be argued, however, that part of the motivation for this is revenge, since the bad guys manage to kill just about all of Wyatt's friends and relations.
Very strong violence, mostly involving the frequent use of guns, as well as shooting and killing. We see blood smears and blood gushing. In one very gory scene, a doctor tries -- and fails -- to remove a bullet from a man's body (with much screaming and yelling). A priest is shot in the head, and other characters are similarly shot. We see gruesome corpses. A little girl is seen cowering, terrified during a shootout.
Allusions to hookers available in the town of Tombstone. The already-married Wyatt Earp becomes interested in a sexy showgirl, Josephine, who is seen as "the devil" in a stage play. (Although, according to the end credits, Earp happily spent the rest of his life with her). Otherwise, there's a good measure of flirting and kissing. There is also a suggestive painting of a girl on a wall.
Strong, but not constant language, including one use of "f--king." We also hear: "s--t," "dick," "damn," "Goddamn," "Christ Almighty," "sons of a bitch," "hell," "piss," "damn," and "Antichrist."
Drinking, Drugs & Smoking
In this Old West town, most secondary characters drink heavily. The hero's best friend, Doc Holliday, drinks very, very heavily and is seen very drunk. Some characters smoke opium. Wyatt Earp's wife takes Laudanum for a headache, and always seems to be in a state of stupor. (She tries to hide her drugs from her husband.) We also see some cigar smoking.
