Both of these have a lot of language (if you care about that) and violence (more than some of the other suggestions, like Poltergeist), but if it were my 14-year-old, I'd be good with either of these. They're both really funny and engaging and not too slow.
It is worth checking Common Sense Media (I ignore the religious overtones you sometimes find there, but the overall explanation of what people might find objectionable in a movie there is usually pretty good).
