If your kids want to see a cool thriller, but you are cautious around big-budget slasher flicks, rent this from Blockbuster and watch it together on a Friday night. Everyone will enjoy themselves, and you won't have to worry about what they're seeing, as this film has little sex, language, and no violence.
Language consists of some "hells" and few "d**n"s. There is some playful sexual innuendo between Jimmy Stewart and Grace Kelly (it isn't exactly beating around the bush, but it isn't vulgar at all) that runs along the lines of her spending the night and there only being one bed. A beautiful ballerina exercises in her underwear, and a man attempts to force himself on an unnamed girl (it appears to be more of an embrace gone too far than an attempted rape).
