One of the movie's pervasive messages is that if you could change any one thing, it should obviously be to make yourself rich. That said, Marty's time travel demonstrates the importance of family (whereas Biff's desire for time travel is rooted solely in greed and materialism). The movie also has a strong theme about not letting what other people think of you bother you.

A character is seen shot by terrorists but escapes injury. A bully makes several threats. Some dark/ominous imagery.

More sexual innuendo than in the original. In addition to a couple of quick kisses between Marty and his girlfriend, there are references to breast implants and size, infidelity and unwanted advances. In one scene, a married male character is shown with his arms draped around two swimsuit-clad groupies in a hot tub.

Words not usually associated with PG movies are used a few times, including "s--t," "bitch," and "a--hole." Other language includes "hell," "stupid," "suckers," "butthead," and "loser."

Product placements include Nike, Pepsi, Texaco, Black & Decker, and AT&T, all of which are sort of poked fun at, since the movie is set in the once-distant future. And, of course, there's the famous DeLorean.

Marty's mother obviously likes to drink, and references are made to her possibly being a "drunk." Biff is shown with a drink in his hand.
