In spite of the keywords, there is no nudity in this movie
The mermaids do not wear bras but have breasts but no nipples
A past relationship between two characters is discussed; some light innuendos ensue. Jack briefly comments that he mistook a convent for a brothel, and Angelica says he seduced and "corrupted" her, who was "innocent".
The mermaids/sirens are clearly not wearing any clothing, but there is no nudity. Their long hair, blurred moments, silhouettes, and strategically placed camera shots block any nudity.
A mermaid is seen laying back with her hair draped down covering her breasts. Shot strategically, no nudity.
A mermaid is seen spinning in a tank of water, it is obvious that she has bare breasts, which is obscured by a slight murkiness of the water, and the fact that she is moving.
A mermaid steps onto dry land and her body changes from part fish to fully human. She ends up naked in front of her captors but nothing is shown but bare limbs. She covers herself with her arms and then crouches to hide her nudity. She is then covered with a button-up shirt from another character. The shirt is not buttoned and cleavage is visible in later scenes. Also, the fact that her naked body is pressed up against him is obvious, since the shirt is only draped over her shoulders.
Another woman's cleavage is seen very briefly about four times.
To prevent a fall, Jack grabs hold of a sign and hangs there for a few seconds until danger is gone, when he looks up his face is in between the ample cleavage of a woman portrayed on the sign.
Jack pulls apart Angelica's blouse to expose a tattoo on her cleavage while giving the viewers a view of her cleavage.
During an attack, Jack starts to lie down in bed with Angelica as she is asleep but she wakes up. Nothing sexual.
At one point a missionary traveling with the pirates suggests an alternative to a plan the pirates had. Jack replies with, "I support the missionary's position."
In one scene Jack holds out his sword to block Angelica from walking further. She responds, "How is it we can never meet without you pointing something at me?"
Jack is pursued by soldiers and ends up crashing into a carriage, carrying an older woman. He begins to kiss her neck in order to bewilder her; she moans, and when he stops, she says, "That's it?"
A female character lies to a male character saying that she is pregnant with his baby and that he was drunk at the time. The male character dismisses her claim by saying that he has never been "that drunk".
A woman often wears cleavage revealing shirts
