Fight for what you believe in. Save your friends in situations of danger. Every man has a price. Eternal damnation is something to be avoided. Even the most amoral among us may someday reveal a scrap of decency underneath.
Characters are chased, stabbed, flogged, shot at, trampled, roasted, and rolled down hills. A sea monster uses its giant tentacles to pluck screaming sailors off ships and swallow up the vessels whole. Davy Jones is an evil, devilish character whose head is a noseless mass of Medusa-like squirming serpents and whose hands are lobster claws. He steals souls of sailors and condemns them to decades of hard labor. Sword fights, shootings, stabbings, and deaths-by-tentacle are rife. Jack wears a necklace of human fingers and toes. Cannibals tie Jack to a stake and suspend him over a fire, but he escapes. Men are caged and hung over an abyss. A severed beating heart is shown in a box. Men are put in cages so their eyes can be plucked out by birds. Elizabeth and William are threatened with hanging. It's implied that cannibals might eat a dog. Davy Jones' crew members are grotesque, scary, and filthy, wearing makeup that makes them look as if they've been left to rot.
Innuendoes and double meanings are rampant, notably involving a compass, swords, and fighting. A voodoo woman acts sultrily, sashaying her hips and giving men come-hither looks. Jack and Elizabeth kiss. Elizabeth says she would like to "have" her fiancé, William.
Characters drink throughout the movie, and Jack refers to alcohol in a positive way ("If this were a dream, there'd be rum").
