The importance of staying "young at heart." Though this is shown through various childish endeavors such as food fights and name-calling, the takeaway is the idea of maintaining a childlike innocence in your interactions with others.
Peril. Kids screaming while trapped in a net. Lengthy sword-fighting scenes. Hook runs his blade through a valiant young boy, killing him. Slapstick violence. Tinkerbell hits Peter Pan in the head. During an impromptu baseball game among pirates, a pirate is shot and killed for trying to steal second base. Hook puts a gun to his head and threatens suicide. Gunfire.
Peter Pan is kissed on the mouth by several mermaids at the same time. When pirates walk through a wharf, there is a brief scene where the madam of a house of ill repute tells her prostitutes to "paint your faces, ladies!"
"Ass," "hell," "bitch." Euphemism: "Dead man's dinghy." A lengthy exchange of name-calling between a boy and the lead character, which includes phrases such as "near-sighted gynecologist" and culminates in Peter screaming "Eat me!" at the young boy. A father screams "Shut up!" at his kids while in the midst of a heated phone conversation.
In Tinkerbell's home, a wall is made out of a Master Card, and one of the seats is a packet of Certs breath mints.
Wine drinking. The lead character takes a large sip of whiskey and stumbles. One reference to being high on drugs.
