Common Sense Note
Parents need to know that Alien is a classic of sci-fi horror, and while not as gory as most horror films, it's too intense for younger viewers. In its most iconic scene, a character is killed after an alien burrows out of his chest, shooting blood everywhere. Unrelenting suspense permeates every scene after the first 15 minutes. While the deaths of the characters aren't always shown, gruesome killing at the hands (actually, tentacles) of the alien is strongly implied. One of the characters smokes, and all of them in their panicked states use profanity.
Sexual
Content
Toward the end, a character takes off her space uniform, stripping down to a half-shirt and panties. In one of the pods, there are pictures of naked women, breasts shown.
Violence
A character sitting down to dinner with fellow crew members falls into convulsions, then dies a bloody death as an alien burrows out of his chest. One by one, characters are killed by the alien. While their deaths aren't always shown, gruesome deaths are strongly implied. Characters shoot a flamethrower and fire a cattle prod while trying to defend themselves against the alien. Horror movie suspense of the "What's that around the corner?" variety abounds.
Language
Expletives when faced with alien outbreak: "f--k off," "son of a bitch," "horses--t," "hell."
Social
Behavior
A bloodthirsty alien, devoid of remorse or conscience, kills off crew members of a deep-space mining ship. But Ripley conveys the strong message to never give up and to do eveything you can to try to save your friends and co-workers.
