Common Sense Note
Parents need to know that I.Q. is a cute, quirky 1950s-set romantic comedy starring Tim Robbins, Meg Ryan, and, as Albert Einstein, Walter Matthau. It's light and breezy, and there's hardly anything in the way of iffy content. You can expect a smattering of salty language ("shut up," "hell," and "jeez" are each said once), some kissing and embracing, and a bit of innuendo (a passing reference to "making love," a double-entendre joke about "premature ignition" in a car, and the like), but overall this is a tween-friendly story about learning to think with your heart as well as your head. Characters do deceive and manipulate others to achieve their ends, but their intentions are for the best, truth wins out in the end, and it's all quite lighthearted.
Sexual
Content
Kissing/embracing. Some innuendo (brief references to "premature ignition" and "making love"). References to a natural phenomenon in Maui that feels like a million kisses on your skin and/or an enormous tongue licking your entire body. Catherine's fiance rebuffs her attempts to get physical during a dinner party. Some longing looks. A character is briefly referred to as "the chimp pimp." Atoms are described once as "sexy."
Violence
A man falls out of a tree (no injuries). Some fairly reckless-looking motorcycle riding, without helmets (not required during the movie's time period). A couple wrestles on the ground; a woman slaps a man on the face. The subjects of a time-deprivation experiment are loudly agitated. Talk of attaching electrodes to experimental mice's genitals.
Language
Infrequent use of words including "shut up," "hell," and "jeez." Barely heard use of "bitch." Some name-calling ("troglodyte," "idiot," "rat man") and crude references ("how are they hanging?"). One use of a derogatory term ("dago").
Social
Behavior
Ultimately a celebration of love, friendship, and learning to think with your heart, the movie also deals quite a bit in deception and manipulation (albeit done with the best of intentions). But characters feel bad about deceiving others and eventually come clean.
Consumerism
Car brands are mentioned by men who work at a garage. Vintage issues of magazines are shown.
Drugs / Tobacco /
Alcohol
Adult characters drink wine and beer with dinner and toast with champagne at a reception.
