Common Sense Note
Parents need to know that Indiana Jones and the Last Crusade has lots of hand-to-hand combat, action-filled chases, and gun fights. Main characters are in near-constant peril, and one is shot point blank and almost bleeds to death. Minor characters are killed in somewhat gruesome ways, including beheading; a bad guy meets his end in a fairly disturbing scene. There's a bit of kissing/banter, and it's implied that two men have slept with the same woman. Language is mild, and there's ultimately a strong message about the importance of the father-son relationship.
It's insinuated that Indiana and his father slept with the same woman. Some kissing/embracing. Banter.
Hand-to-hand combat, action-filled chases (boats, planes, tanks, more), beatings, and gun fights. Bad-guy minions are killed in fairly gruesome ways, including beheading. Indy uses a whip frequently. Henry is shot at point-blank range and almost bleeds to death. Lots of peril. Threat of fire and drowning. At one point, other characters briefly think a main character has died. A bad guy meets his end in a scene that could disturb younger viewers (potential spoiler alert: he ages extremely rapidly and briefly becomes a dessicated, mummy-like being before disintegrating).
Language includes "damn," "my God," and "Jesus Christ" (as an exclamation).
Ingenuity, teamwork, and trying to do the right thing are ultimately rewarded, although some of Indy's methods are iffy. Standing up to bullies (in the form of the Nazi party) is a strong theme. The power of a father-son relationship is explored and emphasized.
Drugs / Tobacco /
A character lights a cigarette (accurate for the era). Indy and another character have champagne; later, Indy has a cocktail.
